ABSTRACT:
A method and apparatus can be arranged with a correlated double sampler circuit (CDS) for processing an output signal from an imaging device such as a charge-coupled device (CCD) image sensor. The CDS circuit includes an amplifier, a set of capacitors that are dynamically configured for sampling and holding operations, and a reduced number of capacitive digital-to-analog converter (CDAC) circuits, all arranged in a ping-pong architecture. The described ping-pong architecture is useful in digital imaging applications such as digital scanners, digital copiers, digital cameras, and digital camcorders, to name a few.
