Abstract
This paper analyzes the drawback of traditional biased folded cascode operational amplifier and proposes a new biased folded cascode operational amplifier.This new circuit restrains the variety of the tail current source of the folded cascode for the variety of input common voltage and mismatch.The new circuit not only stabilizes the operational point of the amplifier and increases the CMRR,but it also reduces the other performance of the amplifier.
