摘要
利用实际集成运算放大器的频率特性,给出了仅由电阻 R 和运算放大器组成的无电容 R 有源滤波电路及其理论分析,并就 R 有源滤波电路参数对滤波特性和电路工作的稳定性影响作了详细讨论,给出了 R
The theory about active R filter circuit only with R and operational amplifier are proposed on the basis of the frequency characteristics of existent integrated operational amplifier.And a detailed disoussion of the influence of the filter circuit parameter on filter characteristics and the stability of circuit are presented.Finally,a fulfiling condition of R active filter parameter is given.
