Abstract
A readout circuit for an image sensor is disclosed. At least one column amplifier (CA) generates a CA reset signal when the column amplifier is reset. A capacitor and a switch are configured to receive a column of the image sensor. A multiplexer is coupled between (a) the capacitor and the switch and (b) an input of the column amplifier. A correlated double sampling (CDS) circuit is used for controllably receiving an output of the column amplifier.
