为了设计多功能电流模式滤波器和进行滤波器的调谐,提出了一种参数独立可调的二阶电流模式滤波器的信号流图及与之相应的MOOCII(多端输出的第2代电流传输器)电流模式滤波器.该滤波器由3个MOCCII、3个电容及4个电阻构成,能产生低通、带通、高通、带阻及全通滤波输出.滤波器的固有频率及品质因数等参数能独立可调,且具有很低的有源及无源灵敏度.对提出的电路进行了计算机模拟,结果证明提出的电路是正确的. In order to design a multi-functional current mode filter and to carry out the tuning of the filter, a signal flow diagram of a second-order current mode filter with independently adjustable parameters and a corresponding MOOCII (multi-terminal output second-generation current transmitter ) Current mode filter. The filter consists of three MOCCII, three capacitors and four resistors form, can produce low-pass, bandpass, high pass, band-stop and all-pass filter output. The natural frequency filter and quality factor The parameters can be independently adjustable and have low active and passive sensitivity.The computer simulation of the proposed circuit shows that the proposed circuit is correct.
