| 摘 要： | 提出一种四阶有源滤波器，由运算跨导放大器和电容（ＯＴＡ－Ｃ）组成。改变输入电路的结构，可以分别做为流模式滤波器和电压模式滤波器使用。每种滤波器均可同时实现四阶高通，带通和低通滤波功能。给出了计算机仿真实验结果。

| Abstract: | A fourth-order active filter is presented, which is composed of operational transconductance amplifiers and capacitors.By changing the structure of its input-circuit,it can be used as a current-mode filter or a voltage-mode filter,and each of the both can simultaneously implement the fourth-order highpass,bandpassand lowpass flter functions.The result of computer simulation is presented at last. |
