一种用传输系数分析负反馈放大电路的简易算法

Using Circuit Transfer Coefficient to Simplify Analysis of The Negative Feedback Amplifies

讨论不同负反馈组态下的端口条件对电路传输系数 GS的影响 ,从而导出闭环下的源增益 Afs和增益 Af之间、闭环输入电阻 rif与输出电阻 rof之间的统一算式。

After discussing the inflience caused by different negative feedback configuration's port conditions on circuit transfer coefficientG s, an united calculation formulae of source gain A· fs and clsed gain A· f, of input resistance r if and output resistance r of are found.
