Abstract
A correlated double sampling (CDS) circuit is provided. The CDS circuit is configured to perform a CDS on a reset signal and an image signal during a CDS phase respectively. The CDS circuit includes a sampling circuit configured to output a difference between a correlated double sampled reset signal and a correlated double sampled image signal, and a feedback unit configured to feedback the difference output from the sampling circuit during a PGA phase to an input of the sampling circuit.
