基于负电阻的二端口电路实现方法及其应用

Realization of Two-port Circuit with OP and Its Application

本文采用运放电路,以二端口电路的短路电导矩阵为例,讨论了对于给定G矩阵参数的二端口电路的实现方法。归纳出几种简单的二端口电路,通过这些二端口的并联来实现任意二端口电路,非常容易理解。将该方法应用于回转器电路的实现中,得到了一种未见于文献报道的回转器实现电路。本文的讨论可供讲授电路理论课程的教师参考。

Taking the short-circuit conductance matrix of two-port circuit as an example,the implementation of two-port circuit for given G-matrix parameters is discussed.Several simple two-port circuits are summarized,and any two-port circuit can be realized by connecting these two-port circuits in parallel.It is very easy to understand.The method is applied to the realization of gyrator circuit,and a gyrator circuit which has not been reported in the literature is obtained.The discussion is helpful for the teaching of circuit theory course.
