Abstract
A Correlated Double Sampling (CDS) integrating circuit and a data converter, the CDS circuit includes a CDS integration module and a level shifting module. The CDS integration module is configured to sample a first input signal and an Operational Amplifier (Opamp) input offset voltage to a sampling capacitor during a first phase; and sample a second input signal and the Opamp input offset voltage to the sampling capacitor during a second phase, and transfer a charge difference generated on the sampling capacitor to an integrating capacitor. The level shifting module is configured to sample an output signal and a common-mode voltage to a level shifting capacitor during a first stage of the first phase and the second phase, and shift a potential of an Opamp output voltage towards the common-mode voltage through the level shifting capacitor in a second stage of the second phase.
