一种新的多功能电流模式滤波器

A New Multifunctional Current Mode Filter

提出了一种新的多功能双二阶滤波器．该滤波器可以实现二阶低通、高通、带通、带阻和全通滤波功能，且同时具有三种不同输出，电路的无源灵敏度很低．ＰＳＰＩＣＥ仿真结果表明该电路可行．

A new multifunctional current mode filter is proposed.The filter can realize second order low pass,high pass,band pass,band stop and all pass filtering functions and has three kinds of output terminals at the same time.The circuit has very low positive sensitivity.PSPICE simulating results show that the proposed circuit is feasible.
