    摘要: A CMOS image sensor that has reduced transistor count is disclosed. The individual pixels are formed by a photodiode and a transfer transistor. An output node receives the signal from the photodiode via the transfer transistor. The output node is shared between multiple pixels. Further, a reset transistor is coupled between a selectable low voltage rail Vss or a high voltage reference Vref and the output node. The gate of an output transistor is then coupled to the output node. Both the reset transistor and output transistors are shared between multiple pixels. Further, the pixels have a mirror symmetry about the output transistor or output node.

    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.

The pixel array includes a plurality of pixel cells each including a floating diffusion (“FD”) node and a photosensitive element coupled to selectively transfer image charge to the FD node. The bit line is coupled to selectively conduct image data output from a first group of the pixel cells. The supplemental capacitance node line is coupled to the FD node of a second group of the pixel cells different from the first group. The control circuit is coupled to the supplemental capacitance node line to selectively increase the potential at the FD node of each of the pixel cells of the second group by selectively asserting a FD boost signal on the supplemental capacitance node line.
