Abstract
Pixel circuits, capable of operating in either 'snapshot' or 'rolling integration' mode, and compatible with a conformal photodiode coating. Preferred embodiments of the present invention are compatible with these coating materials, as well as others, including amorphous Silicon. The preferred pixel circuits includes additional transistors not provided in prior art pixel circuits to divert leakage current away from integration nodes when not integrating, to reset the integration node, and to buffer and select the integrated voltage.
