摘要:提出了一种用CCCII实现的有高输出阻抗的电流模式全通滤波器,该电路仅使用2个CCCII模块,通过选取4个不同的电阻或电容可构成8种不同的全通滤波器,且阻抗匹配、增益可调,PSPICE仿真结果验证了理论分析的正确性.

Abstract: A new configuration for the realization of current-mode all-pass filters with high output impedance is presented.It can realize all-pass filtering function using two Current Controlled Conveyors (CCCIIs) connected to four RC one-port elements.Eight different realizations for the proposed configuration are given in tabular form,which exhibit identical transfer functions but differ in the number of passive components,component matching constraints,possibility of electronically gain adjustment and other properties.PSpice simulation for an actual circuit is conducted,and the result shows that the proposed circuit is valid and effective.

Key words: current-mode, current controlled conveyor, all-pass filter
