Abstract:
1. An imager, comprising: a pixel for providing an image output signal, said pixel comprising: a photosensor for accumulating charge; a storage region for storing charge transferred from the photosensor; a transfer transistor for transferring charge from the photosensor to the storage region, wherein a drain of the transfer transistor is connected to the photosensor and a source of the transfer transistor is connected to the storage region; a photosensor reset transistor connected between a selectively enabled control line and a gate of said transfer transistor, the photosensor reset transistor for transmitting a first control signal to a gate of the transfer transistor to reset the charge accumulated on the photosensor in accordance with said first control signal and a second control signal applied to a gate of said photosensor reset transistor.
