Abstract
A single-stage class AB multipath operational amplifier is presented. The proposed amplifier uses the previously idle devices in a folded-cascode amplifier in the signal path and a flipped-voltage follower cell to build the class AB operation. It results in enhanced unity-gain bandwidth and DC gain and large slew rate with the same power consumption as the folded-cascode amplifier. Circuit level analysis and simulation results are provided to verify the effectiveness of the proposed amplifier.
