Abstract

See full text

A CDS circuit is provided. The CDS circuit includes a signal compressor which compresses each of a pixel signal and a ramp signal using capacitive dividing and outputs a compressed pixel signal and a compressed ramp signal, and a comparator which compares the compressed pixel signal with the compressed ramp signal and outputs a comparative signal corresponding to a comparison result.
