    摘要： An image sensor includes a pixel array, a bit line, a supplemental capacitance node line, and a control circuit. 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.

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 to selectively couple a supplemental capacitance to the FD nodes of the second group in response to a control signal. In various embodiments, the first and second group of pixel cells may be the same group or a different group of the pixel cells and may add a capacitive boost feature or a multi conversion gain feature.
