Patent ID: 8063422

Claim:
An apparatus comprising: a first MOS imaging pixel comprising: a photodetector configured to receive incident radiation and produce a photocurrent in response to the incident radiation; a MOS field effect transistor (MOSFET) configured as a source follower, the MOSFET having a body, a source, and a gate, the source being directly connected to the body such that they remain at substantially the same electrical potential, and the gate being coupled to the photodetector to receive a voltage signal resulting at least partially from integration of the photocurrent and indicative of an amount of the incident radiation; a precharge transistor coupled to the photodetector and configured to inject a precharge on the gate of the MOSFET; and a switch comprising a p-channel transistor and an n-channel transistor, the switch coupled between the source of the MOSFET and a column line and configured to provide a voltage on the source of the MOSFET to the column line, wherein the column line interconnects a plurality of MOS imaging pixels including the first MOS imaging pixel.
