Novel high performance CMOS current conveyor
In this paper a new CMOS second generation current conveyor based on a novel voltage follower architecture is presented. Both class-A and class-AB topologies are proposed. Results from 0.8 μm designs supplied at 3.3 V show very low resistance at node X (<50 Ω), high frequency operation (∼100 MHz), high precision in the voltage and current transference and reduced offset. As basic application examples, a voltage-to-current converter and a current feedback operational amplifier have been considered.
