摘 要:
介绍用集成运算放大器(цA741)组成的基本放大器和高性能放大器的理论分析及调试方法。理论分析了反相放大器、差动放大器的闭环增益、输入阻抗、输出阻抗。并介绍几种典型的应用放大器:由цA741组成的基本放大器、T型网络高输入阻抗放大器、自举高阻反相放大器;基本差动放大器;高基模范围的差动放大器。对这些实际电路的调整方法做了重点介绍,调试准确无误。[著者文摘]

Abstract:
This paper deals with the theoretical analysis of the basic amplifier and the high qualitative amplifier and how to adjust them. Introduce several typical application amplifier: basic reverse proportion amplifier, reverse amplifier with high impedance made up of T meshwork, reverse amplifier with booster high impedance, basic differential amplifier; differential amplifier of high radical mode bound. Mostly introduce the adjust method of these practice circuit, debug to nicety, and widely use in practice.[著者文摘]
Key words:
type T meshwork ; high input impedance ; booster high impedance ; high basic mode
