Abstract
A nsw correlated double sampling (CDS) scheme is proposed which improves th e operation of an integrator with a large parasitic capacitor at the: input node of an oy-amp. Tt suppresses the effects of the 1/f noise and offset v oltage of the op-amp, as well as the kTC charge noise from the parasitic ca pacitor. It also reduces charge injection and clock feedthrough effects.
