本文讨论了分析有源网络中几种简单而实用的运放框图,提出了选择主反馈支路的概念,从而把一级运放电路等效为一个简单的结点求和框图,十分有利于复杂有源网络的工程分析。
This article discusses the analysis of several simple and practical op-amp block diagrams in active networks, and proposes the concept of selecting the main feedback branch so that the first-stage op amp circuit is equivalent to a simple junction sum block diagram that is very advantageous Engineering Analysis of Complex Active Networks.
