| 摘 要： | 以AOA电流模式多路输出积分器和AOA电流模多路输出比例电路为基础,设计了多功能二阶电流模式滤波器。该电路既可通过改变输入信号的作用点,从同一端口分别实现高通、带通和低通滤波,又可从同一端口输入信号,从不同端口同时实现高通、带通和低通滤波,真正实现了多功能滤波。计算机仿真证明该滤波器正确有效。

| Abstract: | Based on a current-mode integrator and proportion circuit multiple outputs by AOA, multifunctional second-order current-mode filter was proposed. Functions, such as high-pass, band-pass and low-pass filtering, can be realized by changing position of input signal and output signal. Multifunctional filtering was really realized. Computer simulation was conducted, and the result shows that the presented circuit is valid and effective |
