General Solutions of the Operational Amplifiers

以普通适用的矩阵分析,代替以“虚地”为基础的传统运放分析方法。文中阐述了数学模型的建立,导出了一个公式。该公式适用于无论电路繁简、反馈类型的任何网络。

This paper is written from the angle of the admittance matrix analyucal method for the operational amplifier, instead of the traditional method based on thc“virtual earnh'. In this paper the author presents the eatablishment of the mathematical model and develops a formula, which applies to any networks of feedback type, whether it is complicated or simple.
