Abstract
A photodiode produces photogenerated charges in response to exposure to light. An integration period collects the photogenerated charges. Collected photogenerated charges in excess of an overflow threshold are passed to an overflow sense node. Remaining collected photogenerated charges are passed to a sense node. A first signal representing the overflow photogenerated charges is read from the overflow sense node. A second signal representing the remaining photogenerated charges is read from the sense node.
