Abstract
A wide dynamic range photodetector comprising a photosensitive region for generating signal electrons in response to being illuminated, a collection region for storing the signal electrons generated within the photosensitive region, a shift register for receiving and outputing the signal electrons from the collection region, and a transfer gate intermediate the photosensitive region and the collection region for alternately facilitating transfer of the signal electrons from the photosensitive region for storage in the collection region, and isolating the photosensitive region from the collection region while the signal electrons are being output via the shift register.
