An improved CMOS differential voltage current conveyor with double input and double output terminal (DIDOCC) was presented, based on wide linear transconductance and common mode detection circuit. The circuit has current-controlled function and restrains even harmonics and common-mode interference. Simulation results showed that, at supply voltage between -1.5 V and 1.5 V, the circuit had a total static current of about 300 mA and a differential voltage input dynamic range from -0.9 V to 0.9 V. Based on the DIDOCC circuit, a fully-differential second-order bandpass filter was designed, and simulated results were in good agreement with theoretic calculation.
