深度负反馈放大电路中的“虚短”和“虚断”分析

Analysis of “virtual short circuit” and “virtual open circuit” exsiting in amplifier circuit with strong negative feedback.

本文将理想集成运放中的两个重要概念“虚短”和“虚断”推广到深度负反馈情况下的任意放大电路中 。

WT5BZ]This article extends two important concept“Virtual short circuit”and “Virtual open circuit”in ideal integrated operational complifier circuit to All amplifiers circuit with strong negative feedback,making the calculation and analysis in amplifiers circuit with strong negative feedback simple.
