Abstract
An electronic device disclosed herein includes a photodiode, and a plurality of storage components each configured to independently sample and hold charges from the photodiode during each of a plurality of integration periods without discharging the held charge between successive integration periods of the plurality thereof. Each storage component accumulates the charges from the photodiode for a given time window during each integration period, with the given time window for each storage component being different than the given time window for each other storage component. Readout circuitry is configured to transfer the charges from each storage component to a readout node in a respective read period for that storage component. The photodiodes and storage components are not configured to be reset between successive time windows during each integration period.
