ABSTRACT:
A correlated double sampling (CDS) amplifier for an image sensing device includes a plurality of capacitors and a switching network coupled to the plurality of capacitors and to a pixel of the image sensing device. The switching network is configured to couple the capacitors in parallel as an initial CDS difference voltage is generated, and then is configured to couple the capacitors in series for generating a final CDS difference voltage that is a multiple of the initial CDS difference voltage.
