摘要

本文提出一个只用电阻和运算放大器的R有源滤波器的新电路。该电路的特点是:具有四个输出端

可实现多种功能[低通（LP）、带通（BP）、高通（HP）、带阻（BS）和全通（AP）]

且灵敏度低

工作稳定。在其中的两个输出端上(V

和V

或V

和V

可实现上述五种功能

除V

外

每个输出端至少可实现两种功能。文中给出了设计方程、运用极限和实验。实验结果证实了理论的正确性。

Abstract

A new circuit of active R filter which uses only resistors and operational amplifiers is presented. It has all advantages of such active R filter. The reactance elements in circuit have been eliminated

then it can be integrated. It is suitable for medium or low Q

even high frequency applied. It has very low sensitivities with respect to all passive and active parameters

the stability of circuit is very high.
