摘　　要：基于运放的负反馈电路有四种拓扑结构:电压串联负反馈放大电路,电压并联负反馈放大电路,电流串联负反馈放大电路,电流并联负反馈放大电路。本文将深入讨论四种拓扑结构的原理。There are four topological structures in the negative feedback circuit based on up amp： amplifying circuit with negative feedback of voltage series, amplifying circuit with negative feedback of voltage shunt, amplifying circuit with negative feedback of current series and amplifying circuit with negative feedback of current shunt. This paper discusses the principle of four topological structures in depth.
