Abstract
The charge collection control circuit generates a time-varying voltage that is used to control the charge collection process in an MOS photodetector for the purpose of obtaining greater dynamic range. Control is exercised either by means of an integration control electrode that controls the flow of charge from a charge-collecting region to a sink or by means of a transfer electrode that controls the flow of charge from the charge-collecting region to a charge-transport region through which the collected charge flows to an output circuit.
