Abstract
A solid-state image sensor () with very high sensitivity approaching the single-photon limit is realized with three modular building blocks: (a) a pixel (. . . ) with a photo-site, intermediate photo-charge storage capability as used for correlated double sampling, and an electronic circuit for signal buffering or amplification, (b) a column or row signal line () to which a plurality of such pixels (. . . ) is connected using transistor switches, incorporating a low-pass filter (), and (c) a readout circuit () to which the row signal lines (. . . ) are connected, consisting of a plurality of analog amplifiers (. . . ) with an analog multiplexer (). Photo-generated signals are read out and the reset level is subtracted either in the analog or in the digital domain, to implement a correlated-double-sampling method.
