单运放电流型二阶有源滤波电路

The Single Operation Amplifer Current-mode 2nd Active Filter Circuit

提出两种使用单运放的电流型滤波电路,每种电路均可同时实现带通、低通和高通滤波功能,

This paper gives two kinds of single operational amplifer current-mode active filter circuits, They can realize lowpass, highpass and bandpass without changing circuit topology and element,
