集成运放电路的信号流图分析

An Analysis of Signal Flow Graph of the Integrated Operational Amplifier Circuit

一个线性电网络存在着由其线性方程组确定的信号流图。而线性方程组的代数变换与图的变换存在着对应关系,通过图的变换可直接对一个线性电网络求解。根据这一原理,本文论述了信号流图在集成运放电路分析中的应用,并通过两个实例加以说明。

There exists the signal flow graph determined by its linear system of equations in a linear electric network and there is a corresponding relationship between algebraic transformation of linear system of equations and graph transformation,through which we can direct towards a linear electric network solution.Based on this theory,this paper discusses the application of the signal flow graph in the analysis of the integrated operational amplifier circuit,and illustrates it through two cases.
