提出了一种基于差动差分电流传输器(DDCC)的单输入五输出的通用电压模式双二阶滤波器,其电路由两个DDCC+、三个电阻和两个接地电容构成。该滤波器结构简单,不需外加任何电路,能同时实现低通、全通、高通、带阻及带通功能,固有频率ω与品质因素Q能独立调节,并具有较低的无源灵敏度,PSPICE仿真结果验证了电路的正确性。 A single-input, five-output universal voltage mode biquad filter based on differential differential current transmitter (DDCC) is proposed. The circuit consists of two DDCC +, three resistors and two ground capacitors. The filter has a simple structure and can realize low-pass, all-pass, high-pass, band-stop and band-pass functions at the same time without any external circuit. The natural frequency ω and quality factor Q can be independently adjusted and have lower passive sensitivity, PSPICE simulation results verify the correctness of the circuit.
