摘要
本文讨论有源 R 滤波器的设计方法。它的基本原理是利用运算放大器的单极点传输特性模拟感纳和容抗。文中给出了一只无外接电容的二阶有源低通和一只六阶有源低通的设计实例。
This paper describes technigues of design active R filter using only risistors and operationnl amplifiers.It is a simulation method that allow single-pole trans- fer function of oA and risistance divider to simulate inductive immittance and ca- pacitive impedance.Actual examples of a second-order actile low-pass filter and a sixth-order active low-pass filter without extemal capasitors are given here.
