一种电流模式多功能滤波器结构

Simple CC-Based Current-Mode Biquadratic Configration

提出了一种简单的电流模式多功能滤波器结构，具有一个输入端和三个输出端，可以实现低通、高通、带通、全通和陷波功能，不需要任何严格匹配关系．该结构中只使用了６个ＣＣ器件，两个接地电阻和两个接地电容，结构十分简单且无源灵敏度很低．

A simple current-mode universal biquadratic configuration with one input and three outputs is presented, which is possible to realize lowpass. highpass.bandpass. allpass and notch filtering characteristics. No strict copsponent matching condition is needed. The proposed structure contains only six current conveyors, two grounded resistors and two grounded capacitors. The passive sensitivity is very low.
