Abstract
Systems and methods are provided that facilitate reducing noise within sampled video information in a CMOS sensor imager. A multi-capacitor sample and hold can capture multiple samples of video information during at least partially overlapping time intervals. The multi-capacitor sample and hold can include a plurality of capacitors and a plurality of sampling switches, wherein each of the sampling switches can be coupled to a respective one of the plurality of capacitors. The plurality of sampling switches can be closed at a substantially concurrent time to begin capturing samples with the plurality of capacitors. Thereafter, the plurality of sampling switches can each be opened at respective disparate times to collect differing noise samples with each of the plurality of capacitors. A readout component can combine (e.g., average) the samples obtained by the plurality of capacitors, thereby reducing noise levels.
