ABSTRACT:
A correlated double sampling circuit has a sampling capacitor equally divided into a plurality of portions. In the correlated double sampling circuit, an input signal is sampled at a plurality of sampling points and an averaging switch is closed to obtain an average value of a plurality of sampling values obtained by sampling. High frequency noise superimposed on the input signal is thus reduced and a difference between the average values of the plurality of sampling values obtained by sampling is output.
