Patent ID: 7910993

Claim:
An accumulated charge control (ACC) floating body MOSFET (ACC MOSFET), adapted to control nonlinear response of the MOSFET when the MOSFET is operated in an accumulated charge regime, comprising: a) a MOSFET having a floating body, wherein the MOSFET is biased to selectively operate in the accumulated charge regime, and wherein accumulated charge is present in the body of the floating body MOSFET when the MOSFET is biased to operate in the accumulated charge regime; and b) an accumulated charge sink (ACS) operatively coupled to the body of the MOSFET, wherein, when the MOSFET is operated in the accumulated charge regime, an ACS bias voltage (V ACS ) is applied to the ACS to control the accumulated charge in the MOSFET body or to remove the accumulated charge from the MOSFET body via the ACS; wherein the MOSFET includes a gate, drain, source, and a gate oxide layer positioned between the gate and the body, and wherein the MOSFET operates in the accumulated charge regime when the MOSFET is biased to operate in an off-state (non-conducting state), and wherein charge accumulates within the body in a region proximate the gate oxide; wherein the MOSFET body includes a channel region including a gate modulated conductive channel between the source and the drain, and wherein the source, drain and channel have carriers of identical polarity when the MOSFET is biased to operate in an on-state (conducting state), and wherein the MOSFET operates in the accumulated charge regime when the MOSFET is biased to operate in the off-state and when the accumulated charge has a polarity that is opposite to the polarity of the source, drain and channel carriers.
