Abstract: This paper gives the discussion on a kind of analysis method, Node Admittance Matrix Method, for negative feedback amplifying circuits. This analysis method has generalised other four methods used in analyzing feedback amplifiers. It is an active network method determined by behaviours of computers, and has advantages of simpler process, more exact result and being more easily adopted to computer-aided analysis (CAA).

摘要： 本文讨论负反馈放大电路的一种分析方法——节点导纳矩阵分析法。此法将四种类型的反馈放大器分析统一化,是根据计算机的特点提出的一种有源网络分析法。此法步骤简单、结果精确,采用矩阵运算,易于在计算机上作辅助分析。
