用有源RC滤波器实现网络综合的方法

Network Synthesis with Active RC Filter

在模拟滤波器的设计中,综合转移函数的方法总的来说分为两类,即用无源网络综合和用有源网络综合实现。目前常用的是用有源RC网络综合实现滤波器,实现有源RC滤波器的基本方法有直接法和级联法。文中介绍了级联法实现有源RC滤波器的典型过程,用此方法列举了一个高通滤波器的实现,并得到了正确的仿真图。

Methods of transfer function synthesis during the design of analog filter can be divided into mainly two kinds： using passive network or active network to realize a filter. At present, the commonly used method is to use an active RC network to realize the filter. The basic methods of realizing the active RC filter are direct method and cascade method. They are described in this article. And the article carefully describes the typical process of how to realize an active RC filter using cascade method. In addition, taking a high pass filter＇s realization for example and a correct simulation diagram is obtained in the end. That the described method efficient is proved.
