一、概述在晶体管放大电路的化简分析过程中,要运用一些网络定理对晶体管电路的小信号等效电路进行化简,这些定理包括:(1)电流源裂变定理;(2)受控源替代定理;(3)受控源化简定理。这些定理有关书籍已有阐述。在此,我们介绍如何实际应用这些定理,来简化晶体管放大电路的分析过程和方法。为此我们首先简要地介绍一下这些基本网络定理。 I. Overview In the process of simplifying the transistor amplifier circuit, some network theorems are used to simplify the small signal equivalent circuit of the transistor circuit. These theorems include: (1) current source fission theorem; (2) controlled source Substitution theorem; (3) Controlled source simplification theorem. These theorems have been elaborated on books. Here, we introduce how to actually apply these theorems to simplify the analysis process and method of transistor amplifier. To this end, we first briefly introduce these basic network theorem.
