本文采用电流传送器CCII+/-的模块单元设计实现高阶椭圆函数滤波器，实现方法为对所设计的无源高阶滤波器用信号图（SFG）进行模块化综合，用电流传送器CCII+/-实现SFG中的各个模块单元。所实现的有源CCII+/-滤波器中所有电阻，电容都接地，适于全集成。
In this paper, a high-order elliptic function filter is implemented by using the CCII +/- module design of the current transmitter. The method is to modularize the signal pattern (SFG) of the passive high-order filter designed, and the current transmitter CCII +/- Achieve the SFG in the various modules unit. All the resistors and capacitors in the active CCII +/- filter implemented are grounded for full integration.
