ABSTRACT:
A pixel includes five transistors, a photodetector and a storage node. A first transistor is coupled between the photodetector and the storage node. A second transistor includes a second transistor source and a second transistor drain. The second transistor source is coupled to the storage node. The second transistor drain is coupled to an output drain voltage. A third transistor includes a third transistor drain. The third transistor is coupled between the photodetector and a pixel reset voltage. The third transistor drain is coupled to the pixel reset voltage. The pixel reset voltage is different than the output drain voltage.
