  • Patent number: 10873716
    Abstract: A pixel cell and row select and row driver circuits include two column bias circuits and row driver circuits, one placed at the right and one placed at the left side of the array of pixel cells. The digital control signals for the two sets of bias and row driver circuits enter at the center top or bottom of the array of pixel cells and drive the circuits symmetrically. The combination of two-sided row driver and column bias helps eliminate any signal delay and bias difference between the left and right side of the pixel cell array. More significantly this circuit construction can minimize horizontal shading in the resulting image.
