本文提出了一种基于多输出端电流控制电流传输器(multiple outputs current controlled conveyors II)的双二阶电流模式滤波器电路,该滤波器结构简单,仅包含2个有源器件、2个接地电容。在不改变内部电路的情况下只需改变外部输入电流的接入方式和接入数目就可以实现二阶低通、高通、带通、带阻、全通滤波功能,面向实际电路完成了PSpice仿真,结果表明提出的电路正确有效。
This paper presents a bi-second-order current mode filter circuit based on multiple outputs current controlled conveyors II. The filter has a simple structure and consists of only two active devices and two ground capacitors . The second-order low-pass, high-pass, band-pass, band-stop, all-pass filtering can be realized by simply changing the external input current access method and the number of accesses without changing the internal circuit. The results show that the proposed circuit is correct and effective.
