Abstract
A correlated double-sampling circuit for sampling an input signal received from a pixel sensor circuit via an input line. According to one embodiment, a first switch selectively couples a junction of first terminals of a first capacitor and a second capacitor to the input line. A second switch selectively couples an output node coupled to a second terminal of the second capacitor to a reference voltage. A third switch selectively couples the output node to an output line.
