Abstract:
In a pixel having an electronic shutter, a method of increasing the retention time of the electronic shutter is disclosed. A reset signal is employed to drive a diode node to a predetermined voltage immediately after integration is completed. A sample signal is employed to control a pass gate. The sample signal includes a state where the sample signal is a negative voltage.
