Current conveyor (a current mode circuit) is a good choice for low voltage applications as it provides high gain-bandwidth product. Current mode design technique offers voltage independent, high bandwidth in analog circuits with properties of accuracy and versatility in a wide range of applications. In this paper we present a rail-to-rail low voltage (±1.5 V) differential current conveyor (LVDCC) circuit in standard CMOS technology that is suited for low voltage operation. The proposed circuit uses a low-voltage-current-mirror. The output range is −1.3 to +1.4 voltage which is nearly rail-to-rail. This proposed differential current conveyor is suitable for low power CMOS mixed-mode designs.
