Patent ID: 8829407

Claim:
A pixel array of an imaging system comprising: a plurality of pixel cells arranged in columns and rows, wherein each pixel cell of the plurality of pixel cells comprises: a photosensor operable to sense an amount of light impinging on the photosensor; a transfer transistor operable to selectively pass an image signal corresponding to the amount of sensed light towards an output node of the pixel cell; a reset transistor operable to selectively couple the pixel cell to a reset voltage, wherein each pixel cell can generate a reset signal corresponding to the reset voltage; a reset control line for controlling the reset transistor; and a transfer control line for controlling the transfer transistor, wherein the reset control line is a shared control line shared with a transfer transistor of a previous pixel cell and the transfer control line is a shared control line shared with a reset transistor of a next pixel cell, and wherein each pixel cell of the plurality averages at most one control line per pixel cell; and a source follower transistor operable to buffer the image signal and selectively provide the image signal to the output node, wherein a drain of the source follower transistor is coupled directly to a pixel array power line of the pixel array.
