本文将原在控制系统中发展的根轨迹理论改用于有源网络的分析与综合。基于这些理论,确定RC网络的型式,它们与集成运算放大器组合,可实现复极点对;研究员反馈放大器设计中的一个重要问题,即如何选定基本放大器与反馈网络,使同时获得低敏感度及可接受的频率响应与暂态响应。
In this paper, the original theory of root locus developed in control system is changed to the analysis and synthesis of active network. Based on these theories, the types of RC networks are determined and they are combined with an integrated operational amplifier to realize the repolarization point pair. An important issue in the design of the feedback amplifier for researchers is how to select the basic amplifier and the feedback network so as to obtain both low sensitivity and Acceptable frequency response and transient response.
