微光夜视器材已成为部队装备中重要的组成部分,目前所装备的微光夜视仪产生的都是单色图像[2]。
单色图像的重大缺陷是信噪比较低且图像缺乏深度感,不利于探测和分辨目标。
人眼能够分辨大约几十种灰度级和大约1 000种颜色[3],利用人眼对彩色相对高的分辨力和灵敏度的特点,实现彩色夜视以极大提高目标探测和识别概率。
Fisheye Series | DH-IPC-EBW81242NHeat MapThe built-in IVS features heat map functionality that tracks and stores daily, weekly, monthly, and yearly people flow through a defined scene and produces a configurable report. The system uses this data to produce a Heat Map, a two-dimensional representation of data that provides an immediate visual summary of information.Dewarping ModeFisheye dewarping solves the problem of distortion in the circular panoramic view. The camera offers multiple dewarping modes for different installations and configurations with a Dahua NVR or via the Web interface. Each dewarping mode offers options to adjust each scene.Smart IRWith IR illumination, detailed images can be captured in low light or total darkness. The camera's Smart IR technology adjusts the intensity of camera's infrared LEDs to compensate the distance of an object. Smart IR technology prevents IR LEDs from whitening out images as they come closer to the camera. The camera's integrated infrared illumination provides high performance in extreme low-light environments up to 10 m (33 ft).High Efficiency Video Coding (H.265)The H.265 (ITU-T VCEG) video compression standard offers double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate, as compared to older video compression technologies. H.265 offers such impressive compression by expanding the pattern comparison and difference-coding, improving motion vector prediction and motion region merging, and incorporating an additional filtering step called sample-adaptive offset filtering.EnvironmentalDahua cameras operate in extreme temperature environments, rated for use in temperatures from –30° C to +60° C (–22° F to +140° F). The camera complies with an IK10 impact rating making it capable of withstanding the equivalent of 5 kg (11.02 lbs) of force dropped from a height of 40 cm (15.75 in.). Subjected to rigorous dust and waterimmersion tests and certified to the IP67 Ingress Protection rating makes it suitable for demanding outdoor applications.•1/1.7-in. 12 MP Progressive-scan STARVIS™ CMOS Sensor •12 MP (4000 x 3000) at 30 fps Maximum Resolution •Triple Stream Encoding•Smart H.265+ and Smart H.264+ Dual Codecs •Built-in Microphone •Multiple Dewarp Modes•Analytics+ Functions — People Counting and Queue Management•Intelligent Video System with Intelligent Business Analysis •Maximum IR Distance 10 m (33 ft)•IP67 Ingress Protection and IK10 Vandal Resistance •Five-year Warranty*Heat Map QueuingSystem OverviewDahua Fisheye Cameras provide detailed panoramic views in a compact, low-profile design. The progressive-scan sensor combined with a fisheye lens provide a high-quality 360° panorami c view without blind spots, making the camera the ideal solution for wide and open areas, such as airports, shopping malls and banks. The camera offers Analytics+ functions at the edge – performing complex real-time perimeter people counting and queue management. The IP67 environmental protection rating and the IK10 vandal resistance ensure the camera operates in the harshest environments.FunctionsPeople CountingThe camera uses complex real-time people counting algorithms to count the number of people in up to four (4) distinct, user-defined regions. The function can trigger an alarm when a threshold setting is exceeded or when a wait time has exceeded a minimum time. People counting is ideal for measuring the number of customers entering or exiting a location and to monitor groups of people in a distinct location.Queue ManagementThis Analytics+ function monitors four (4) user-defined regions where people wait in line (or queue). Queue Management triggers an alarm when the number of people in line exceeds a minimum threshold or when the time a person waits in line is greater than the minimum queue time. The function displays each target in real-time and offers various report output formats.Intelligent Video System (IVS)IVS is a built-in video analytic algorithm that delivers intelligent functions to monitor a scene for Tripwire violations, intrusion detection, andabandoned or missing objects. A camera with IVS quickly and accurately responds to monitoring events in a specific area.*Warranty applies to products sold through an authorized Dahua Dealer.AccessoriesRev 001.002© 2020 Dahua Technology USA.

Box 9106, Norwood, MA 02062-9106, U.S.A.Tel: 781/329-4700World Wide Web Site: FUNCTIONAL BLOCK DIAGRAMPRODUCT HIGHLIGHTS1.Voltage Output Multiplying DACThe AD7845 is the first DAC which has a full 4-quadrant multiplying capability and an output amplifier on chip. All specifications include amplifier performance.2.Matched Application ResistorsThree application resistors provide an easy facility for gain ranging, voltage offsetting, etc.3.Space SavingThe AD7845 saves space in two ways. The integration of the output amplifier on chip means that chip count is reduced.The part is housed in skinny 24-lead 0.3" DIP, 28-terminal LCC and PLCC and 24-terminal SOIC packages.GENERAL DESCRIPTION The AD7845 is the industry’s first 4-quadrant multiplying D/A converter with an on-chip amplifier. It is fabricated on the LC 2MOS process, which allows precision linear components and digital circuitry to be implemented on the same chip.The 12 data inputs drive latches which are controlled by stan-dard CS and WR signals, making microprocessor interfacing simple. For stand-alone operation, the CS and WR inputs can be tied to ground, making all latches transparent. All digital inputs are TTL and 5 V CMOS compatible.The output amplifier can supply ±10 V into a 2 k Ω load. It is internally compensated, and its input offset voltage is low due to laser trimming at wafer level. For normal operation, R FB is tied to V OUT , but the user may alternatively choose R A , R B or R C to scale the output voltage range.FEATURES12-Bit CMOS MDAC with Output Amplifier 4-Quadrant MultiplicationGuaranteed Monotonic (T MIN to T MAX )Space-Saving 0.3" DIPs and 24- or 28-Terminal Surface Mount PackagesApplication Resistors On Chip for Gain Ranging, etc.Low Power LC 2MOSAPPLICATIONSAutomatic Test Equipment Digital AttenuatorsProgrammable Power Supplies Programmable Gain Amplifiers Digital-to-4–20 mA Converters查询AD7845JN供应商捷多邦,专业PCB打样工厂,24小时加急出货(V DD = +15 V, ؎ 5%, V SS = –15 V, ؎ 5%, V REF = +10 V, AGND = DGND = O V,V OUT connected to R FB.

V SS = –15 V, ؎ 5%. V REF = +10 V. AGND = DGND = O V.)NOTES1Analog Devices reserves the right to ship either ceramic (D-24A) or cerdip(Q-24) hermetic packages.2To order MIL-STD-883, Class B processed parts, add /883B to part number.3E = Leadless Ceramic Chip Carrier; N = Plastic DIP; P = Plastic Leaded ChipCarrier; Q = Cerdip; R = SOIC.AD7845PIN CONFIGURATIONSLCCPLCCDIP, SOICDIGITAL-TO-ANALOG GLITCH IMPULSEThis is the amount of charge injected from the digital inputs to the analog output when the inputs change state. This is nor-mally specified as the area of the glitch in either pA-secs or nV-secs depending upon whether the glitch is measured as a current or voltage. The measurement takes place with V REF =AGND.DIGITAL FEEDTHROUGHWhen the DAC is not selected (i.e., CS is high) high frequency logic activity on the device digital inputs is capacitively coupled through the device to show up as noise on the V OUT pin. This noise is digital feedthrough.MULTIPLYING FEEDTHROUGH ERRORThis is ac error due to capacitive feedthrough from the V REF terminal to V OUT when the DAC is loaded with all 0s.OPEN-LOOP GAINOpen-loop gain is defined as the ratio of a change of output voltage to the voltage applied at the V REF pin with all 1s loaded in the DAC. It is specified at dc.UNITY GAIN SMALL SIGNAL BANDWIDTHThis is the frequency at which the magnitude of the small signal voltage gain of the output amplifier is 3 dB below unity. The device is operated as a closed-loop unity gain inverter (i.e.,DAC is loaded with all 1s).OUTPUT RESISTANCEThis is the effective output source resistance.FULL POWER BANDWIDTHFull power bandwidth is specified as the maximum frequency, at unity closed-loop gain, for which a sinusoidal input signal will produce full output at rated load without exceeding a distortion level of 3%.TERMINOLOGYLEAST SIGNIFICANT BITThis is the analog weighting of 1 bit of the digital word in aDAC. For the AD7845, 1 LSB = V REF212.RELATIVE ACCURACYRelative accuracy or endpoint nonlinearity is a measure of the maximum deviation from a straight line passing through the endpoints of the DAC transfer function. It is measured after adjusting for both endpoints (i.e., offset and gain error are ad-justed out) and is normally expressed in least significant bits or as a percentage of full-scale range.DIFFERENTIAL NONLINEARITYDifferential nonlinearity is the difference between the measured change and the ideal 1 LSB change between any two adjacent codes. A specified differential nonlinearity of +1 LSB max over the operating temperature range ensures monotonicity.GAIN ERRORGain error is a measure of the output error between an ideal DAC and the actual device output with all 1s loaded after offset error has been adjusted out. Gain error is adjustable to zero with an external potentiometer. See Figure 13.ZERO CODE OFFSET ERRORThis is the error present at the device output with all 0s loaded in the DAC. It is due to the op amp input offset voltage and bias current and the DAC leakage current.TOTAL HARMONIC DISTORTIONThis is the ratio of the root-mean-square (rms) sum of the har-monics to the fundamental, expressed in dBs.OUTPUT NOISEThis is the noise due to the white noise of the DAC and the input noise of the amplifier.Typical Performance Characteristics–AD7845Figure 3.Output Voltage Swing vs.Resistive LoadFigure 6.Typical AD7845 Linearityvs. Power Supply Figure 9.Unity Gain Inverter PulseResponse (Small Signal)Figure 4.Noise Spectral DensityFigure 7.Multiplying Feedthrough Error vs. FrequencyTIME – sO U T P U T – m V8010–20220468101214161870200–1040306050Figure 10.Digital-to-Analog Glitch Impulse (All 1s to All 0s Transition)Figure 2.Frequency Response, G = –1Figure 5.THD vs. FrequencyFigure 8.Unity Gain Inverter Pulse Response (Large Signal)AD7845PIN FUNCTION DESCRIPTION (DIP)Pin Mnemonic Description1V OUTVoltage Output Terminal2-11DB11–DB2Data Bit 11 (MSB) to Data Bit 212DGND Digital Ground.

For normal operation this is connected to V OUTCIRCUIT INFORMATION Digital Section Figure 11 is a simplified circuit diagram of the AD7845 input control logic. When CS and WR are both low, the DAC latch is loaded with the data on the data inputs. All the digital inputs are TTL, HCMOS and +5 V CMOS compatible, facilitating easy microprocessor interfacing. All digital inputs incorporate standard protection circuitry.Figure 11.AD7845 Input Control LogicD/A SectionFigure 12 shows a simplified circuit diagram for the AD7845D/A section and output amplifier.A segmented scheme is used whereby the 2 MSBs of the 12-bit data word are decoded to drive the three switches A-C. The remaining 10 bits drive the switches (S0–S9) in a standard R-2Rladder configuration.Figure 12.Simplified Circuit Diagram for the AD7845 D/A SectionEach of the switches A–C steers 1/4 of the total reference cur-rent with the remaining 1/4 passing through the R-2R section.An output amplifier and feedback resistor perform the current-to-voltage conversion givingV OUT = – D × V REFwhere D is the fractional representation of the digital word. (D can be set from 0 to 4095/4096.)The amplifier can maintain ±10 V across a 2 k Ω load. It is inter-nally compensated and settles to 0.01% FSR (1/2 LSB) in less than 5 µs. The input offset voltage is laser trimmed at wafer level. The amplifier slew rate is typically 11 V/µs, and the unity gain small signal bandwidth is 600 kHz. There are three extra on-chip resistors (R A , R B , R C ) connected to the amplifier invert-ing terminal. These are useful in a number of applications in-cluding offset adjustment and gain ranging.AD7845UNIPOLAR BINARY OPERATIONFigure 13 shows the AD7845 connected for unipolar binary operation. When V IN is an ac signal, the circuit performs2-quadrant multiplication. The code table for Figure 13 is givenin Table I.Figure 13.Unipolar Binary Operation Table I.

For high temperature applications, resistors and potenti-ometers should have a low temperature coefficient.BIPOLAR OPERATION(4-QUADRANT MULTIPLICATION)The recommended circuit for bipolar operation is shown in Figure 14. Offset binary coding is used.The offset specification of this circuit is determined by the matching of internal resistors R B and R C and by the zero code offset error of the device. Gain error may be adjusted by varying the ratio of R1 and R2.To use this circuit without trimming and keep within the gain error specifications, resistors R1 and R2 should be ratio matched to 0.01%.The code table for Figure 14 is given in Table II.Figure 14.Bipolar Offset Binary Operation Table II.

In this configuration, the R-2R ladder is connected in the amplifier feedback loop. R FB is the amplifier input resis-tor. As the code decreases, the R-2R ladder resistance increases and so the gain increases.V OUT = –VIN × R DACD × 1R FB , D =0to 40954096 = –V IN ×R DAC D × 1R DAC= –VIN D, since R FB = R DACFigure 15.AD7845 Connected as PGAAs the programmed gain increases, the error and noise also increase. For this reason, the maximum gain should be limited to 256. Table III shows gain versus code.Note that instead of using R FB as the input resistor, it is also possible to use combinations of the other application resistors,R A , R B and R C . For instance, if R B is used instead of R FB , the gain range for the same codes of Table II now goes from l/2to 128.Table III.Gain and Error vs. Input Code for Figure 15Digital Inputs Gain Error (%)1111111111114096/4095 ≈ 10.0410000000000020.0701000000000040.1300100000000080.26000100000000160.5100001000000032 1.0200000100000064 2.0000000100000128 4.00000000100002568.0PROGRAMMABLE CURRENT SOURCESThe AD7845 is ideal for designing programmable currentsources using a minimum of external components. Figures 16and 17 are examples. The circuit of Figure 16 drives a program-mable current I L into a load referenced to a negative supply.Figure 17 shows the circuit for sinking a programmable current,I L . The same set of circuit equations apply for both diagrams.I L = I 3 = I 2 + I 1I 1 = D ×|V IN |RDAC ,D =0to 40954096I 2 = 1R 1 D ×|V IN |R DAC R FB = D ×|V IN |R 1, since R FB = R DAC I L =D ×|V IN |R 1 +D ×|V IN |R DAC= D ×|V IN |R 1×1+R 1R DACNote that by making R1 much smaller than R DAC , the circuitbecomes insensitive to both the absolute value of R DAC and its temperature variations. Now, the only resistor determining load current I L is the sense resistor R1.If R1 = 100 Ω, then the programming range is 0 mA to 100 mA,and the resolution is 0.024 mA.Figure 16.Programmable Current SourceAD7845Figure 17.Programmable Current Sink4–20 mA CURRENT LOOPThe AD7845 provides an excellent way of making a 4-20 mAcurrent loop circuit. This is basically a variation of the circuitsin Figures 16 and 17 and is shown in Figure 18. The applicationresistor R A (Value 4R) produces the effective 4 mA offset.I L = I3 = I2 + I1Since I2 > I1,I L = –V X156=2.54R×R FB+2.5R DAC×D×R FB×1156and since R DAC=R FB=RI L =2.54+D×2.5×1000156mA= [4 + (16 ×D)]mA, where D goes from 0 to 1 withDigital CodeWhen D = 0(Code of all 0s):I L = 4 mAWhen D = 1(Code of all 1s):I L = 20mAThe above circuit succeeds in significantly reducing the circuitcomponent count. Both the on-chip output amplifier and theapplication resistor R A contribute to this.Figure 18.4–20 mA Current LoopAPPLICATION HINTSGeneral Ground Management: AC or transient voltagesbetween AGND and DGND can cause noise injection into theanalog output. The simplest method of ensuring that voltages atAGND and DGND are equal is to tie AGND and DGNDtogether at the AD7845. In more complex systems where theAGND and DGND intertie is on the backplane, it is recom-mended that two diodes be connected in inverse parallel be-tween the AD7845 AGND and DGND pins (IN914 orequivalent).Digital Glitches: When a new digital word is written into theDAC, it results in a change of voltage applied to some of theDAC switch gates. This voltage change is coupled across theswitch stray capacitance and appears as an impulse on the cur-rent output bus of the DAC. In the AD7845, impulses on thisbus are converted to a voltage by R FB and the output amplifier.The output voltage glitch energy is specified as the area of theresulting spike in nV-seconds. It is measured with V REF con-nected to analog ground and for a zero to full-scale input codetransition. Since microprocessor based systems generally havenoisy grounds which couple into the power supplies, theAD7845 V DD and V SS terminals should be decoupled to signalground.Temperature Coefficients: The gain temperature coefficientof the AD7845 has a maximum value of 5 ppm/°C. This corre-sponds to worst case gain shift of 2 LSBs over a 100°C tem-perature range. When trim resistors R1 and R2 in Figure 13are used to adjust full-scale range, the temperature coefficientof R1 and R2 must be taken into account. The offset tempera-ture coefficient is 5 ppm of FSR/°C maximum. This corre-sponds to a worst case offset shift of 2 LSBs over a 100°Ctemperature range.The reader is referred to Analog Devices Application Note“Gain Error and Gain Temperature Coefficient of CMOS Mul-tiplying DACs,” Publication Number E630C-5-3/86.AD78458-BIT MICROPROCESSOR SYSTEMSFigure 22 shows an interface circuit for the AD7845 to the 8085A 8-bit microprocessor. The software routine to load data to the device is given in Table IV. Note that the transfer of the 12 bits of data requires two write operations. The first of these loads the 4 MSBs into the 7475 latch. The second write opera-tion loads the 8 LSBs plus the 4 MSBs (which are held by thelatch) into the DAC.Figure 22.8085A Interface Table IV.

These are the MC68000, 8086 and the TM32010. The AD7845 is treated as a memory-mapped peripheral to the processors. In each case, a write instruction loads the AD7845 with the appropriate data.The particular instructions used are as follows:MC68000:MOVE 8086:MOVTMS32010:OUTFigure 19.AD7845 to MC68000 InterfaceFigure 20.AD7845 to 8086 InterfaceFigure 21.TMS32010AD7845Figure 23 and 24 are the interface circuits for the Z80 and MC6809 microprocessors. Again, these use the same basicformat as the 8085A interface.Figure 23.AD7845 to Z80 InterfaceFigure 24.MC6809 InterfaceDIGITAL FEEDTHROUGHIn the preceding interface configurations, most digital inputs to the AD7845 are directly connected to the microprocessor bus.Even when the device is not selected, these inputs will be con-stantly changing. The high frequency logic activity on the bus can feed through the DAC package capacitance to show up as noise on the analog output. To minimize this digital feedthrough isolate the DAC from the noise source. Figure 25 shows an interface circuit which uses this technique. All data inputs are latched from the busy by the CS signal. One may also use other means, such as peripheral interface devices, to reduce the digitalfeedthrough.Figure 25.AD7845 Interface Circuit Using Latches to Minimize Digital FeedthroughAD7845OUTLINE DIMENSIONSDimensions shown in inches and (mm).C 1189b –1–9/99P R I N T E D I N U .S .A .24-Lead Plastic DIP(N-24)24-Lead Cerdip(Q-24)24-Lead Ceramic DIP(D-24A)28-Terminal Leadless Ceramic Chip Carrier(E-28A)28-Terminal Plastic Leaded Chip Carrier(P-28A)24-Lead SOIC(R-24)。

Improved Image QualityThe new CMOS image sensor and BIONZ XR™ image processing engine in the Alpha 7S III delivers legendary S-series sensitivity with significantly enhanced color reproduction and texture renderings for improved overall image quality. The base ISO has been lowered to 80, resulting in a normal range of 80-102,400 (expandable to 80-409,600 for video and 40-409,600 for stills) to provide more flexible ISO plus wide dynamic range with low noise at all settings. It offers improved image quality by approximately 1 stop of noise reduction in the middle and high sensitivity ranges.The colors and textures of foliage, human skin, and more are ideally and consistently reproduced without dependence on light sources. Gradation rendering has also been refined for better looking skin tones and highlight roll-off in portraits. It also improves AWB (Auto White Balance) performance with a new “Visible light + IR Sensor” that helps to achieve more precise white balance under artificial lighting, including fluorescent and LED lights.Versatile OperabilityAdvanced Autofocus Performance for Hybrid useFor the first time in an Alpha 7S series camera, the Alpha 7S III offers Fast Hybrid AF by combining phase-detection and contrast-detection AF, giving it the ability to track subjects over a wide area with outstanding speed, precision and smoothness, even when using a narrow depth of field. Fine focus expression is possible with Sony’s E-mount lenses.For environments with a lot of movement, Real-time Tracking and Real-time Eye AF are available to maintain constant focus on the intended subject. Sony’s advanced Real-time Eye AF improves detection performance by 30% over the previous system, thanks to the new image processing engine. It ensures accurate, reliable detection, even when th e subject’s face looks away. Real-time Tracking is initiated simply by touching the subject on the screen. Real-time Eye AF is automatically initiated when an eye is detected.Flexible Autofocus Settings for Movie ShootingBased on customer feedback, the camera includes several AF features for professional users including AF Transition Speed in seven settings, to easily create rack-focus transitions, and five AF Subject Shift Sensitivity settings, which allows the user to customize how easily AF will switch or stay with the locked-on subject. Touch Tracking allows user to not only initiate Real-time Tracking, but also compose and shoot while using a gimbal or while shooting solo. It’s now possible to Touch Focus during manual focus mode on the LCD screen or remotely from the Imaging Edge Mobile application17.New Heat-dissipating StructureThe Alpha 7S III’s design has been updated to ensure effective heat dissipation and minimizes overheating — even during extended continuous recording sessions at 4K 60p 10-bit 4:2:2 video lasting an hour or more88. A newly developed unique heat dissipating structure keeps the image sensor and image processing engine temperatures within their normal operating ranges, preventing overheating while maintaining compact body dimensions. The new heat-dissipating structure requires no fan or cabinet vents allowing Alpha 7S III to maintain dust and moisture resistance18.Movie Assist FunctionsFor video on-the-go, the Alpha 7S III is the first Alpha series camera to include Active Mode9 with 5-axis optical in-body image stabilization to support especially difficult handheld movie shooting. It is also the first Alpha series E-mount body to feature a side-opening vari-angle rear screen, perfect for gimbal-mounted shots, complicated angles, handheld operation and more. The screen rotates sideways, up and down, and features a 3.0 type 1.44 million-dot (approx.) touch panel LCD monitor, for optimal visibility even in bright outdoor environments.In addition, the Alpha 7S III provides a selection of new Creative Look with 10 presets that can be used for both photo and video shoots, making it easy to create interesting moods right in the camera to be used as is or customized by the user.A digital audio interface has been added to the camera’s Multi Interface (MI) Shoe for clearer audio recordings from a compatible Sony external m icrophone. Used with Sony’s XLR-K3M XLR Adaptor Kit, the Alpha 7S III provides 4-channel 24-bit digital audio recording capability in an Alpha series camera for the first time. Like other MI shoe accessories, no cables or batteries are required, providing unrestrained freedom for Alpha system moviemaking.Additional movie assist functions include a redesigned monitor display with a bold, clearly visible red frame that makes it clear when recording is in progress even when mounted on a rig or gimbal, custom zoom settings, adjustable white balance while recording, display rotation, interval recording, still extraction from movies and more.Captured by A7S III with SEL2470GMOutstanding Still Image PhotographyThe Alpha 7S III includes a fast Hybrid AF system with 759 phase-detection AF points covering 92% of the image sensor. The camera can also achieve high AF precision to accurately and reliably focus in light down to EV-619, where subjects are difficult to see clearly even with the naked eye. Users can continuously shoot more than 1,000 uncompressed RAW12images at up to 10fps, or up to 8fps in live view mode, with either the mechanical or electronic shutter.The Alpha 7S III also includes the world’s first 9.44 million-dot (approx.), 0.64 type Quad-XGA electronic viewfinder with a high-definition OLED display and refined. The Alpha 7S III viewfinder offers a 0.90x viewfinder magnification20, 41° diagonal field of view, 25mm high eyepoint for clear, low-distortion corner to corner viewing. It is also dust, fog and moisture resistant, extremely responsive, and has switchable modes for different subject types. Every aspect of the Alpha 7S III viewfinder has been designed and refined for a professional workflow.For the first time in one of Sony’s digital cameras, the Alpha 7S III includes HEIF (High Efficiency Image File Format) allowing for smooth 10-bit gradations and advanced compression technology to maintain image quality while significantly reducing file size and saving storage space. HEIF stills shot in this mode can be played back on a compatible SonyHDR (HLG) TV via a direct HDMI Type-A connection from the Alpha 7S III, delivering true-to-life dynamic range21.Versatile Design Made for the ProsCFexpress Type A for High-speed Data TransferIn another world’s first, the Alpha 7S III features two CFexpress Type A compatible media slots which also support UHS-I and UHS-II SDXC/SDHC cards, enabling high write-and-read speeds while keeping the camera body compact in size. CFexpress Type A cards are ideally suited to high-speed continuous RAW still image shooting as well as 4K 120p movie recording at high bit rates22, providing next-generation write speeds that can quickly clear the buffers of cameras that generate high volumes of still image and movie data. High-speed data transfer to a PC is possible at about 1.7 times faster23 than that of SD card. The dual slots can be set to relay mode for extended continuous recording of even the highest bit rate data as well as simultaneous recording and sort by format type recording.Revised Menu System with Enhanced Touch ScreenThe Alpha 7S III also features a revised menu structure for easier navigation and touch-responsive menu operation for faster, more intuitive control. For creators who shoot both stills and movies, separate settings can now be stored for stills and movie shooting for quick transition between the two.High Reliability Gives Creators New FreedomProfessional users need more than just refined features and performance. They also need the reliability and durability demanded of any professional tool. The Alpha 7S III features a redesigned grip for greater comfort and a secure hold, an improved dust removal feature, plus dust and moisture resistance that maximizes reliability in challenging environments. It includes a durable, reliable HDMI Type-A connector, and is the first Alpha series camera to support USB PD (Power Delivery), allowing higher power to be supplied from an external source so that users can continue to record for extended periods with minimal internal battery usage.Advanced Connectivity for Professional Working EnvironmentsThe Alpha 7S III has been designed and configured to support photo and video journalists and sports shooters who need to deliver stills or movies as quickly as possible with several advanced connectivity options.

A12-mW Wide Dynamic Range CMOS Front-End for a Portable GPS Receiver Arvin R.Shahani,Derek K.Shaeffer,Student Member,IEEE,and Thomas H.Lee,Member,IEEEAbstract—This paper describes a CMOS low-noise amplifier (LNA)and mixer intended for use in the front-end of a global positioning system(GPS)receiver.The circuits were implemented in a standard0.35- m(drawn)CMOS process,with one poly and two metal layers.The LNA has a forward gain(S21)of17dB and a noisefigure of3.8dB.The mixer has a voltage conversion gain of03.6dB and a third-order intermodulation intercept point (IP3)of10dBm,input referred.The combination draws12mW from a1.5-V supply.Index Terms—Amplifier noise,CMOS analog integrated cir-cuits,Global Positioning System,low-noise amplifiers,mixers, receivers.I.I NTRODUCTIONT HERE is large enthusiasm in the consumer market for the capabilities of the Global Positioning System(GPS). Manufacturers of cellular telephones,portable computers,and other mobile devices are looking for ways to incorporate GPS into their products.For many of these hand-held devices,one of the primary concerns is battery life.Thus,there is strong motivation to provide good performance at very low power. The viability of a CMOS low-noise amplifier(LNA)within the context of GPS has been demonstrated previously[1]. This paper extends that work to include the mixer and also investigates a differential LNA architecture.The decision for a differential LNA was made to avoid problems caused by substrate coupling in a single-ended design.Section II applies the results of[1]to this paper’s LNA, in addition to discussing the current LNA’s salient features. Section III details the mixer design and addresses the topics of conversion gain,linearity,and noise.Experimental results are presented in Section IV,followed by the authors’conclusions in Section V.II.LNAA.LNA DescriptionFig.1shows a circuit-level description of the LNA.A differential architecture was selected for better rejection of on-chip interference.The penalty for such a decision is that twice the power must be consumed to achieve the same noisefigure as a single-ended version.Manuscript received June30,1997;revised August18,1997.This work was supported by Defense Advanced Research Projects Agency(DARPA)under Contract N65326-96-C-8608and IBM under the IBM Fellowship program. The authors are with the Center for Integrated Systems,Stanford University, Stanford,CA94305-4070USA.Publisher Item Identifier S0018-9200(97)08269-3.Fig.1.LNA circuit diagram.The LNA consists of two stages:the input stage,formed bytransistorson the LNA’s input impedance.Specifically,the Miller effect tends to substantially lower the input impedance,complicating the task of matching to the input.In addition to mitigating the Miller effect,the use of a cascode improves the LNA’s reverse isolation,which is important in the present application for suppressing local oscillator(LO)feedthrough from the mixer back to the LNA’s RF input.Furthermore,because the output of thefirst stage is tuned with spiralinductors,.It should be noted,however,that a noise penalty is incurred when using a cascode.But,with proper attention to the layout of the devices,the additional noise can be minimized,as discussed in the following section.As shown in Fig.2,the LNA must present the proper input impedance to terminate the off-chip RFfilter preceding it.For this purpose,inductive degeneration is employed in the sourcesofFig.2.Block diagram of the receiverfront-end.Fig.3.Single-ended version of the dc biasing technique.goal is to use theminimumlevel.This fraction becomes thereference to which the input devices’common-modethroughis the differential input resistanceand,because gain will bemaximized by doing so.Loss of signal energy,from mistuning or excessively narrow bandwidths,is not an issue,sincetheis the device’s zero-bias drain conductance,andare coefficients describing the magnitude of the noise powers.In addition to these noise sources,the epitaxial layer’s resistance may contribute noise through the body effect.Such epi noise can be accounted for by slightlyincreasingSHAHANI et al.:DYNAMIC RANGE CMOS FRONT-END2063(a)(b)Fig.5.Mixer circuit diagram.(a)Mixer with probe buffer and (b)mixer circuit used in analysis.figure for a specified power consumption and input impedance.Note that this optimum exists because the gate noise and drain noise terms are not fully correlated.Fig.4plots noise figure as a function of input device width and clearly shows an optimum width of about500m because the detailednature of the gate noise was unknown to the authors when this amplifier was designed.However,the curve has a broad minimum,so the achievable noise figure is little affected by using transistors of this width,at least in principle.The discrepancy between the theoretical minimum of 1.8dB and the measured noise figure of 3.8dB will be addressed in Section IV.III.M IXERA.Mixer DescriptionThe mixer consists of the fourtransistors,-match and an RF tank.The-match is to boost the signal voltageacross the mixer’s RF port via an impedance transformation,while the RF tank is used to filter broad-band noise at the RF port of the mixer.As will be discussed later,this filtering is important because multiple frequencies at the mixer’s RF port are converted to the intermediate frequency at the mixer’s IF port.B.Mixer Conversion GainFig.5(b)shows a simplified mixer circuit that is used in the following analysis.1)Definition:The voltage conversion gain for this mixer is found by exciting the circuit with a RFsinusoid,.Therefore,incalculatingit will be assumedthat,which in the frequency

of the LO and LO waveforms.LO is simply a time-shifted version of LObyis the rectangle function.This LO signal will be thereference to which other types of LO signals will be compared,and it is sketched in Fig.7(a).In practice,a square wave drive is difficult to achieve.A more practical and power-efficient method is to resonate the gate capacitances and drive the gatessinusoidally(7)whereis

simplify the switch network with a Th´e venin equivalent network,generatedfrom(8)and the Th´e venin impedance,written as a conductance,isis a mixed versionof.Fig.9illustrates

transistors,it is most important to keep the current through the switches small to reduce nonlinear voltage drops across the devices [3].This criterion is satisfied with the use of a small capacitive load,which presents a high impedance to the output.The remaining nonlinearities consist of parasitic junction capacitances,which are weak nonlinearities.Furthermore,at the RF port,the parasitic junction capacitances are insignificant compared with the large,linear tankcapacitance.Thusthe frequencies in theset,,whereSHAHANI et al.:DYNAMIC RANGE CMOS FRONT-END2067Fig.14.Diephoto.Fig.15.Block diagram of the GPS front-end test setup.However,making the switches very wide increases their contribution to the load capacitance,which eventually reduces conversion gain.Also,LO power increases as the switches are made wider because a smaller inductance must be used to resonate the gates.For afixedm CMOStechnology with only two metal layers.A die photograph is shown in Fig.14.The aspect ratio of the silicon is somewhat unusual because this project was designed to fit in the scribe lane of a wafer that was primarily devoted to other dice.Accordingly,the dimensions are3502.4mm.Fig.15shows how the die was packaged for testing,and important comments regarding testing follow.First,the inter-face between the LNA and the mixer was taken off-chip to facilitate testing only.By doing so,each block could be tested individually.In a real chip,the LNA would interface on-chip directly to the mixer.Second,the probe buffer,following the mixer,is used to measure the mixer’s output.It was designed so that its linearity does not interfere with the mixer linearity measurement.In a real chip,an IF amplifier would replace the probe buffer,and since test equipment no longer needs to be driven,design of the IF amplifier can proceed withoutTABLE IIGPS F RONT -E ND P ERFORMANCE SUMMARYhaving to drive a50-2068IEEE JOURNAL OF SOLID-STATE CIRCUITS,VOL.32,NO.12,DECEMBER1997Fig.16.Noise figure versus device width for R in =100 andR in =40 .the complete amplifier has more than one noise contributor;however this is not sufficient to account for the discrepancy.A measurement of the input impedance of the LNA revealed the primary reason for the difference.The real part of the input impedance was found to be only40-differential.This gross difference ispartially due to the influence of the overlap capacitance of the input devices,which lowers the impedance seen at the gates of those devices.This behavior was observed in simulations of the LNA’s input impedance,but unfortunately,the impact of the reduced impedance on the noise figure was not fully appreciated at the time.Furthermore,increasing the inductance of the source spiralinductorsm is substantiallyremoved from the optimum point on the40-curve.These compounding effects illustrate thepenalty in undershooting the desired input impedance.The revised prediction anticipates a 3.2-dB noise figure from the input pair alone.Thus,the observed total noise figure of 3.8dB is reasonable,given that other devices in the circuit contribute noise in a second-order fashion.For example,the cascode devices,the load inductors,and the output stage transistors all have noise,which contributes some small amount to the noise figure.The forward gain (S21)and noise figure are plotted in Fig.17.One salient feature of the differential LNA architecture that merits discussion is its reverse gain (S12),which was measured to be less than3.6dB.The measurement wasperformed with the input port of the mixer impedance matched to100--match network,the expected voltage con-version gain should be close to6dB for the voltage attenuation from matching the input port andoftheat resonance,corresponding to a totalnetwork3.5dBm in a100-if the LO were integrated with the mixer.Indeed,a higher impedance could be achieved with spiral inductor tuning of the LO port to further reduce LO power.The single-sideband (SSB)noise figure of the mixer is estimated to be 10dB based on noise figure measurements of the mixer/buffer combination.Given the gain of the preceding LNA,the mixer contributes 0.3dB to the noise figure of the LNA/mixer combination.The IP3of the combination is approximately43dBm.SHAHANI et al.:DYNAMIC RANGE CMOS FRONT-END2069Fig.18.Mixer two-tone IP3measurement.V.C
