Abstract
An active pixel sensor array sampling system includes a plurality of video circuits and reset circuits. A video circuit generates a video voltage from each one of the pixels of a column of pixels. An associated reset circuit generates a reset voltage for each of the pixels of a column of pixels. The video circuits and the reset circuits are closed loop sample and hold circuits. The active pixel sensor array is integrated on an integrated circuit.
