摘　　要：提出了一种基于多输出电流控制电流传输器的通用高阶电流模式滤波器的系统综合设计方法,该方法通过对n阶通用电流模式滤波器的传递函数进行数学分析,将其分解为n个无损积分器级联的形式,由此提出的电路结构简单,仅由n个有源器件,n个接地电容构成。并只要通过改变输入电流的接入方式和接入数目就可以实现不同的滤波功能,便于集成,面向实际电路完成P sp ice仿真。The paper presents a new general synthesis method for the nth order current mode filter based on MOCCCⅡ （multiple outputs current controlled conveyors Ⅱ）. The method is based on the analytical solution of a single, nth-order generic filter transfer function and the generation of n number of realizable transfer functions using lossless integrators. The filter structure presented simply contains n active elements and n grounded capacitors. Various kinds of filters can be realized just by changing the amount and mode of joining external current signals without changing internal circuit structure and the amount of elements. So the circuit is convenient to be integrated. Pspice simulation for actual circuit is conducted, and the result shows that the presented circuit is valid and effective.
