Abstract: | In this paper a new class-AB CMOS second generation current conveyor (CCII) based on a novel high-performance voltage follower topology is proposed. Post-layout simulation results from a 0.8 m design supplied at 3.3 V show very low resistance at node X (<50 ), high frequency operation (100 MHz), high precision in the voltage and current transference and reduced offset. As application examples, a V-I converter and a current feedback operational amplifier (CFOA) have been implemented. The latter presents slew-rate levels higher than ±100 V/s. |
