Patent ID: 8817154

Claim:
An image sensor including a pixel array, the image sensor comprising: a first photosensitive region of a first pixel disposed in or on a substrate layer to accumulate an image charge in response to light incident upon the first pixel; and first pixel circuitry of the first pixel disposed in or on the substrate layer, the first pixel circuitry including: a first transfer-storage transistor coupled between the first photosensitive region and a first charge-storage area to transfer the image charge from the first photosensitive region to the first charge-storage area; and a first output transistor having a channel coupled between the first charge-storage area and a floating diffusion region to selectively transfer the image charge from the first charge-storage area to the floating diffusion region, wherein a gate of the first output transistor is coupled to a first fixed voltage potential and the image charge is selectively transferred from the first charge-storage area to the floating diffusion region in response to a control signal applied to a gate of the first transfer-storage transistor, wherein the first output transistor is a junction gate field-effect transistor.
