A low-noise active pixel circuit is disclosed that efficiently suppresses reset (kTC) noise by using a compact preamplifier consisting of a photodetector and only three transistors of identical polarity, in conjunction with ancillary circuits located on an imager's periphery. The use of only three transistors...http://www.google.fr/patents/USRE43314?utm_source=gb-gplus-shareBrevet USRE43314 - Compact active pixel with low-noise image formation
