摘要:
An image sensor pixel includes a photosensitive region and pixel circuitry. The photosensitive region accumulates an image charge in response to light incident upon the image sensor. The pixel circuitry includes a transfer-storage transistor, a charge-storage area, an output transistor, and a floating diffusion region. The transfer-storage transistor is coupled between the photosensitive region and the charge-storage area. The output transistor has a channel coupled between the charge-storage area and the floating diffusion region and has a gate tied to a fixed voltage potential. The transfer-storage transistor causes the image charge to transfer from the photosensitive region to the charge-storage area and to transfer from the charge-storage area to the floating diffusion region.
