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

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.
