本文对电路分析理论中的Miller对定理进行了新的延拓,推导出的另外三个推论使得Miller,定理的应用范围大大地扩展了,它不仅适用于并——并相连的二端对网络分析,而且还适用于串——串相连、并——串相连及串——并相连的二端对网络分析,从而使常规二端对网络的分析更加简化了。从给出的应用举例分析可知,这些推论用于小信号负反馈放大器的分析之中尤其简便。 In this paper, Miller adds a new extension to the theorem in circuit analysis theory, and deduces three other inferences which make the application of Miller’s theorem extend greatly. It is not only applicable to the parallel-connected two-terminal network Analysis, but also for two-end-to-network analysis of string-string concatenation, concatenation-string concatenation and concatenation-concatenation, thus simplifying the conventional two-end analysis of the network. From the analysis of application examples, we can see that these corollaries are especially convenient for the analysis of small signal negative feedback amplifier.
