本文通过对BJT和FET工作原理和结构的分析及类比，将BJT构成的放大电路的分析方法通过一定的变换直接用于FET构成的放大电路的分析。这样将BJT放大电路和FET放大电路的分析方法统一起来，实现仅仅使用BJT放大电路的一套分析方法完成两种放大电路的分析和计算，可以简化FET放大电路的计算。关键词：BJT；FET{放大电路；化归分析方法
Abstract：Through the analysis and comparison of the operaTIon principle and structure of BJT and FET，the paper introduces that the way of analyzing the amplifying circuit composed of BJT can be applied in the analysis of the circuit composed of FET by means of some changes．Then the method of analyzing BJT amplify circuit and FET amplify circuit can be united as one．And the analysis of the two kinds of amplify circuit can be realized by the method of BJT analysis only：Based on this method，the caculaTIon of FET amplify circuit is simplified．Keywords：BJT；FET；amplify circuit；analysis method
