Abstract
Official abstract text for this publication.
A correlated double sampling (CDS) circuit includes a correction circuit configured to receive an input pixel signal through a first node via a column line, correct the input pixel signal, and output the corrected pixel signal through a second node; and a comparator including first and second input terminals, the first input terminal being connected to the second node and being configured to receive the corrected pixel signal, and the second input terminal configured to receive a ramp signal, the comparator being configured to compare the corrected pixel signal with the ramp signal and output a comparison signal indicating a result of the comparing, wherein the correction circuit includes, a first capacitor connected between the first and second nodes, and one or more metal lines disposed adjacent to the first capacitor, and wherein at least one other capacitor is formed by the first capacitor and the metal line.
