New ± 0.75 V Low Voltage Low Power CMOS Current Conveyor

In this paper a new low voltage low power class AB CMOS second generation current conveyor (CCII) based on Rail-to-Rail folded cascode Op-Amp is presented, with a great performance. The proposed CCII provides very low input impedance at X-port, very high input impedance at V-port, accurate voltage and current tracking with low offset, and wide bandwidth. As an application, a four quadrant analog multiplier has been built based on the proposed CCII. The proposed CCII performance has been investigated by Pspice simulation program using TSMC 0.18 mu m CMOS technology. The presented CCII is supplied at +/- 0.75 V.
