ABSTRACT:
A correlated double sampling circuit comprising an input node comprising a first plate of input capacitor and an output node. A first plate of a feedback capacitor is connected to the output node and a second plate of the feedback capacitor is connected to a second plate of the input capacitor. An input transistor has a gate connected to the second plate of the input capacitor, a source connected to a first supply voltage rail, and a drain connected to the output node. A load transistor has a gate connected to a bias node, a drain connected to the output node, and a source connected to a second supply voltage rail. A reset transistor is connected between output node and the second plate of the input capacitor, and has a gate connected to a reset signal line.
