第十章 Operational Amplifiers:介绍差分放大电路的概念,应用和工作原理。10.1集成运放中的电流源电路:本节来考虑一种利用前面讲解的模块化电路,构成的集成运算放大电路。
10.2零点漂移和差模信号共模信号:本节讲解了零点漂移的概念,这是直接耦合方式所带来的一个缺点,为了克服零点漂移,我们在集成运算放大器的输入端采用了差分放大输入,我们讲解了差模信号,共模信号的基本概念,通过对信号的分解,我们很容易理解差动放大电路对零点漂移的抑制能力。
10.3差动放大电路分析:本节主要来分析差动放大电路的工作原理。
10.4差动放大电路的传输特性:本节来看当输入和输出为大信号时,电路的特性有什么变化。
10.5带恒流源的差动放大电路及本章总结:本节主要介绍带恒流源的差动放大电路,并对本章进行总结。
