| 摘 要： | 本文讨论用导纳矩阵描述多节点运算放大器电路的有用方法。从散射方程出发,求得从无源网络导纳矩阵到有源网络导纳矩阵的转换规则。通过观察,直接由网络写出导纳矩阵,并由其求解电路。还以运算放大器校相器为例,说明如何利用此法有效地计算网络函数和输入导纳。

| Abstract: | This paper discusses an useful method by which the multiple nodes circuit composed of the operational amplifier is described using admittance matrix. On the basis of the scattering equation, some rules of transferring passive admittance matrix to active admittance matrix are obtained. By observing the network, the admittance matrix is written directly and thus circuit can be solved. The example of phase equalizer shows that this method can efficiently calculate the network function and input admittance. |
