Active pixel image sensor having a shared amplifier read

摘要

An image sensor having a plurality of pixels arranged in a series of row and columns comprising: a semiconductor substrate having a plurality of pixels formed in rows and columns with at least two row adjacent pixels and at least two column adjacent pixels formed within the substrate; and at least one electrical function integrated within the adjacent pixels that is shared between the adjacent pixels. The electrical function can be either a contact region or an electrical circuit used in implementing either a photogate, a transfer gate, a reset gate, a row select gate, an amplifier drain, an output node, a floating diffusion contact, a reset drain, a lateral overflow gate, an overflow drain or an amplifier.
