PART 1UNIT 1A Electrical Networks 电路电路或电网络由以某种方式连接的电阻器、电感器和电容器等元件组成。
如果网络不包含能源，如电池或发电机，那么就被称作无源网络。
换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。
在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。
因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。
就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。
在数学上表达为:u=iR(1-1A-1)式中u=电压，伏特；i=电流，安培；R=电阻，欧姆。
纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。
因此可得到：U=Ldi/dt式中di/dt=电流变化率，安培/秒；L=感应系数，享利。
电容两端建立的电压正比于电容两极板上积累的电荷q。
因为电荷的积累可表示为电荷增量dq的和或积分，因此得到的等式为u=，式中电容量C是与电压和电荷相关的比例常数。
由定义可知，电流等于电荷随时间的变化率，可表示为i=dq/dt。
因此电荷增量dq等于电流乘以相应的时间增量，或dq=idt，那么等式(1-1A-3)可写为式中C=电容量，法拉。
归纳式(1-1A-1)、(1-1A-2)和(1-1A-4)描述的三种无源电路元件如图1-1A-1所示。
注意，图中电流的参考方向为惯用的参考方向，因此流过每一个元件的电流与电压降的方向一致。
有源电气元件涉及将其它能量转换为电能，例如，电池中的电能来自其储存的化学能，发电机的电能是旋转电枢机械能转换的结果。
有源电气元件存在两种基本形式：电压源和电流源。
其理想状态为：电压源两端的电压恒定，与从电压源中流出的电流无关。
因为负载变化时电压基本恒定，所以上述电池和发电机被认为是电压源。
另一方面，电流源产生电流，电流的大小与电源连接的负载无关。

It is laser trimmed to provide a maximum error of ±0.3 mV ± 0.3% of reading with sine wave inputs. Furthermore, it maintains high accuracy while measuring a wide range of input waveforms, including variable duty-cycle pulses and triac (phase)-controlled sine waves. The low cost and small size of this converter make it suitable for upgrading the performance of non-rms precision rectifiers in many applications. Compared to these circuits, the AD736 offers higher accuracy at an equal or lower cost.The AD736 can compute the rms value of both ac and dc input voltages. It can also be operated as an ac-coupled device by adding one external capacitor. In this mode, the AD736 can resolve input signal levels of 100 μVrms or less, despite variations in temperature or supply voltage. High accuracy is also maintained for input waveforms with crest factors of 1 to 3. In addition, crest factors as high as 5 can be measured (introducing only 2.5% additional error) at the 200 mV full-scale input level.The AD736 has its own output buffer amplifier, thereby pro-viding a great deal of design flexibility. Requiring only 200 μA of power supply current, the AD736 is optimized for use in portable multimeters and other battery-powered applications.The AD736 allows the choice of two signal input terminals: a high impedance FET input (1012 Ω) that directly interfaces with High-Z input attenuators and a low impedance input (8 kΩ) that allows the measurement of 300 mV input levels whileoperating from the minimum power supply voltage of +2.8 V, −3.2 V. The tw o inputs can be used either single ended or differentially.The AD736 has a 1% reading error bandwidth that exceeds 10 kHz for the input amplitudes from 20 mV rms to 200 mV rms while consuming only 1 mW.The AD736 is available in four performance grades. The AD736J and AD736K grades are rated over the 0°C to +70°C and −20°C to +85°C commercial temperature ranges.The AD736A and AD736B grades are rated over the −40°C to +85°C industrial temperature range. The AD736 is available in three low cost, 8-lead packages: PDIP, SOIC, and CERDIP.PRODUCT HIGHLIGHTS1. The AD736 is capable of computing the average rectified value, absolute value, or true rms value of various input signals.2. Only one external component, an averaging capacitor, is required for the AD736 to perform true rms measurement.3. The low power consumption of 1 mW makes the AD736 suitable for many battery-powered applications.4. A high input impedance of 1012 Ω eliminates the need for an external buffer when interfacing with input attenuators.5. A low impedance input is available for those applications that require an input signal up to 300 mV rms operating from low power supply voltages. SPECIFICATIONSAt 25°C ± 5 V supplies, ac-coupled with 1 kHz sine wave input applied, unless otherwise noted. Specifications in bold are tested on all production units at final electrical test. Results from those tests are used to calculate outgoing quality levels. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.THEORY OF OPERATIONAs shown by Figure 18, the AD736 has five functional subsections: the input amplifier, full-wave rectifier (FWR), rms core, output amplifier, and bias section. The FET input amplifier allows both a high impedance, buffered input (Pin 2) and a low impedance, wide dynamic range input (Pin 1). The high impedance input, with its low input bias current, is well suited for use with high impedance input attenuators. The output of the input amplifier drives a full-wave precision rectifier that, in turn, drives the rms core. The essential rms operations of squaring, averaging, and square rooting are performed in the core using an external averaging capacitor, C AV. Without C AV, the rectified input signal travels through the core unprocessed, as is done with the average responding connection (see Figure 19).A final subsection, an output amplifier, buffers the output from the core and allows optional low-pass filtering to be performed via the external capacitor, CF, which is connected across the feedback path of the amplifier. In the average responding connection, this is where all of the averaging is carried out. In the rms circuit, this additional filtering stage helps reduce any output ripple that was not removed by the averaging capacitor, C AV.TYPES OF AC MEASUREMENTThe AD736 is capable of measuring ac signals by operating as either an average responding converter or a true rms-to-dc converter. As its name implies, an averageresponding converter computes the average absolute value of an ac (or ac and dc) voltage or current by full-wave rectifying and low-pass filtering the input signal; this approximates the average. The resulting output, a dc average level, is scaled byadding (or reducing) gain; this scale factor converts the dc average reading to an rms equivalent value for the waveform being measured. For example, the average absolute value of a sine wave voltage is 0.636 times V PEAK; the corresponding rms value is 0.707 ×V PEAK. Therefore, for sine wave voltages, the required scale factor is 1.11 (0.707/0.636).In contrast to measuring the average value, true rms measurement is a universal language among waveforms, allowing the magnitudes of all types of voltage (or current) waveforms to be compared to one another and to dc. RMS is a direct measure of the power or heating value of an ac voltage compared to that of a dc voltage; an ac signal of 1 V rms produces the same amount of heat in a resistor as a 1 V dc signal.Mathematically, the rms value of a voltage is defined (using a simplified equation) asThis involves squaring the signal, taking the average, and then obtaining the square root. True rms converters are smart rectifiers; they provide an accurate rms reading regardless of the type of waveform being measured. However, average responding converters can exhibit very high errors when their input signals deviate from their precalibrated waveform; the magnitude of the error depends on the type of waveform being measured. For example, if an average responding converter is calibrated to measure the rms value of sine wave voltages and then is used to measure either symmetrical square waves or dc voltages, the converter has a computational error 11% (of reading) higher than the true rms value (see Table 4).CALCULATING SETTLING TIME USING FIGURE 16Figure 16 can be used to closely approximate the time required for the AD736 to settle when its input level is reduced in amplitude. The net time required for the rms converter to settle is the difference between two times extracted from the graph (the initial time minus the final settling time). As an example, consider the following conditions: a 33 μF averaging capacitor, a 100 mV initial rms input level, and a final (reduced) 1 mV input level. From Figure 16, the initial settling time (where the 100 mV l ine intersects the 33 μF line) is approximately 80 ms.The settling time corresponding to the new or final input level of 1 mV is approximately 8 seconds. Therefore, the net time for the circuit to settle to its new value is 8 seconds minus 80 ms, which is 7.92 seconds. Note that because of the smooth decay characteristic inherent with a capacitor/diode combination, this is the total settling time to the final value (that is, not the settling time to 1%, 0.1%, and so on, of the final value). In addition, this graph provides the worst-case settling time because the AD736 settles very quickly with increasing input levels.RMS MEASUREMENT—CHOOSING THE OPTIMUM VALUE FOR CAV Because the external averaging capacitor, C AV, holds the rectified input signal during rms computation, its value directly affects the accuracy of the rms measurement, especially at low frequencies. Furthermore, because the averaging capacitor appears across a diode in the rms core, the averaging time constant increases exponentially as the input signal is reduced. This means that as the input level decreases, errors due to nonideal averaging decrease, and the time required for the circuit to settle to the new rms level increases. Therefore, lower input levels allow the circuit to perform better (due to increased averaging) but increase the waiting time between measurements. Obviously, when selecting C AV, a trade-off between computational accuracy and settling time is required.RAPID SETTLING TIMES VIA THE AVERAGE RESPONDING CONNECTION Because the average responding connection shown in Figure 19 does not use the C AV averaging capacitor, its settling time does not vary with the input signal level. It is determined solely by the RC time constant of CF and the internal 8 kΩ resistor in the ou tput amplifier’s feedback path.DC ERROR, OUTPUT RIPPLE, AND AVERAGING ERRORFigure 20 shows the typical output waveform of the AD736 with a sine wave input applied. As with all real-world devices, the ideal output of VOUT = VIN is never achieved exactly. Instead, the output contains both a dc and an ac error component. As shown in Figure 20, the dc error is the difference between the average of the output signal (when all the ripple in the output is removed by external filtering) and the ideal dc output. The dc error component is therefore set solely by the value of the averaging capacitor used. No amount of post filtering (that is, using a very large CF) allows the output voltage to equal its ideal value. The ac error component, an output ripple, can be easily removed by using a large enough post filtering capacitor, CF. In most cases, the combined magnitudes of both the dc and ac error components need to be considered when selecting appropriate values for Capacitor CAV and Capacitor CF. This combined error, representing the maximum uncertainty of the measurement, is termed the averaging error and is equal to the peak value of the output ripple plus the dc error.As the input frequency increases, both error components decrease rapidly; if the input frequency doubles, the dc error and ripple reduce to one quarter and one half of their original values, respectively, and rapidly become insignificant.AC MEASUREMENT ACCURACY AND CREST FACTORThe crest factor of the input waveform is often overlooked when determining the accuracy of an ac measurement. Crest factor is defined as the ratio of the peak signal amplitude to the rms amplitude (crest factor = V PEAK/V rms). Many common waveforms, such as sine and triangle waves, have relatively low crest factors (≤2). Other waveforms, such as low duty-cycle pulse trains and SCR waveforms, have high crest factors. These types of waveforms require a long averaging time constant (to average out the long periods between pulses). Figure 8 shows the additional error vs. the crest factor of the AD736 for various values of C AV.APPLICATIONSCONNECTING THE INPUTThe inputs of the AD736 resemble an op amp, with noninverting and inverting inputs. The input stages are JFETs accessible at Pin 1 and Pin 2. Designated as the high impedance input, Pin 2 is connected directly to a JFET gate. Pin 1 is the low impedance input because of the scaling resistor connected to the gate of the second JFET. This gate-resistor junction is not externally accessible and is servo-edto the voltage level of the gate of the first JFET, as in a classic feedback circuit. This action results in the typical 8 kΩ input impedance referred to ground or reference level. This input structure provides four input configurations as shown in Figure 21, Figure 22, Figure 23, and Figure 24. Figure 21 and Figure 22 show the high impedance configurations, and Figure 23 and Figure 24 show the low impedance connections used to extend the input voltage range.中文翻译运算真有效值RMS平均整流值绝对值提供满量程200mV范围内输入电压(较大输入的输入衰减器)高输入阻抗:1012Ω低的输入偏置电流:25 pA最大值精度高:±0.3 mV±0.3%的读入波顶因数的有效值转换提升到5宽供电范围:+ 2.8V,−3.2V到16.5 V低功率:最大200mA就可正常运行缓冲输出电压没有外部协议需要规定准确性AD737-是一个芯片断电也可使用的非缓冲电压输出的版本总体描述AD736是一个低功率、精密、真有效值单块集成电路的直流转换器。
