Abstract:
An image sensor of various embodiments includes a pixel array. The pixel array includes a pixel having a photodiode and a transfer gate. The pixel array in various embodiments further includes an antiblooming channel extending from the photodiode to either (i) a pixel output area, or (ii) a drain of a source follower transistor. A method of some embodiments includes (i) driving from a first row driver one or more control signals over one or more control lines to one or more pixels, and (ii) driving from a second row driver the one or more control signals over the one or more control lines to the one or more pixels.
