一种高频高Q电流型有源滤波器电路

An Active Filter of Current Type for Higher Frequency and Higher Quality Factor Q

本文提出一种适用于高频的具有较高Ｑ值的电流型有源滤波器电路。该电路使用了２只ＣＣⅡ器件和一只运算放大器，不必改变电路的结构可以同时实现５种双二次函数。给出了计算机模拟实验结果。

We proposed an active filter of current type for higher frequency andhigher quality factor Q· In the same circuit condition using two cc Ⅱ and One operation am-plfier,five biquadratic functions can be realized independently。Circuit experimental resultsand computer simulation results are concordance。
