description/ordering information
The TL08x JFET-input operational amplifier family is designed to offer a wider selection than any previouslydeveloped operational amplifier family. Each of these JFET-input operational amplifiers incorporateswell-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit. The devices featurehigh slew rates, low input bias and offset currents, and low offset-voltage temperature coefficient. Offsetadjustment and external compensation options are available within the TL08x family.

3/119十万种考研考证电子书、题库视频学习平台圣才电子书给定量。(2)开环控制特点:开环控制是按给定值控制,控制方式比较简单,但控制精度受到原理上的限制。(3)闭环控制特点:闭环控制为偏差控制,可以使反馈回路中的干扰信号得到抑制,因而控制精度较高,但闭环控制有可能使系统不稳定。2.在经典控制理论中,负反馈控制是一种最基本的控制方式,也是一种常用的校正方式,试举例论述采用负反馈控制的优点。[南开大学研]答:负反馈的特点可以从“负”字上得到很好的理解,它主要是通过输入、输出之间的差值作用于控制系统的其他部分。这个差值就反映了我们要求的输出和实际的输出之间的差别。控制器的控制策略是不停减小这个差值,以使差值变小。负反馈形成的系统,控制精度高,系统运行稳定。3.画出负反馈控制系统的组成框图,并说明各环节的作用。[东北大学研]答:负反馈控制系统的组成框图如图1-1所示。图1-1(1)定值环节:产生参考输入或设定值。(2)比较环节:用于产生偏差信号用来控制。(3)放大环节:使偏差信号有足够大的幅值和功率。

Highly Regulated DC Power Supplies
Abstract-The design and application of highly regulated dc power supplies present
many subtle, diverse, and interesting problems. This paper discusses some of these
problems (especially inconnection with medium power units) but emphasis has been
placed more on circuit economics rather than on ultimate performance.Sophisticated
methods and problems encountered in connection with precision reference supplies
are therefore excluded. The problems discussed include the subjects of temperature
coefficient,short-term drift, thermal drift, transient response degeneration caused by
