Abstract
Disclosed is a pipelined analog-to-digital converter which includes a digital correction circuit configured to measure and correct a pipelined conversion stage gain error and an offset error due to a finite voltage gain operational amplifier and capacitor mismatch. The pipelined analog-to-digital converter includes a pipelined conversion stage error measuring and correcting circuit measuring and correcting an error generated from an conversion stage, so that an error of a conversion stage is minimized and a chip realization area and power consumption are reduced.
