运用齐次性定理分析理想运算放大器

Analysis of Ideal Arithmetical Amplifier by Homogeneity Theorem

根据理想运算放大器线性应用的特点,运算电路的传统分析方法是采用"虚短"和"虚断"的概念分析输出与输入的运算关系。在电路理论中运用齐次性定理分析线性网络十分方便。为了简化理想运算电路的分析方法,运用齐次性定理,采用"倒推法"分析了几种常用的运算电路的输出与输入的运算关系,得出了与传统分析方法同样的结果。结果表明,用该定理分析理想运算放大器简单方便、快速准确。

The traditional analysing of arithmetical circuit is analysing the operation relationship between input and output adopt the virtual short circuit and opening Concept,according to ideal arithmetical amplifier＇s character. Using homogeneity theorem Analysis Linear network is very Convenient in circuit theory. To simplify analysis method of ideal arithmetical amplifier, the theorem of homogeneity is used in this paper, and several operational eircui（s output and input relationship is analyzed by inverse method, the output is same as traditional output. The result indicate that using the theorem analysis ideal arithmetical amplifier is easy,fast and accurate.
