Abstract:
1. An accumulated charge control (ACC) NMOSFET (ACC NMOSFET), adapted to process RF signals, and adapted to control nonlinear response of RF signals processed by the ACC NMOSFET, comprising: a) an NMOSFET having a floating body, a gate, a source, a drain and a gate oxide layer between the gate and the body, wherein the NMOSFET is selectively biased to operate in an accumulated charge regime, and wherein, but for an accumulated charge control structure, accumulated charge accumulates within the body in a region proximate to the gate oxide when the NMOSFET is biased to operate in the accumulated charge regime; and b) the accumulated charge control structure comprising an accumulated charge sink (ACS) coupled to the body of the NMOSFET, wherein when the NMOSFET is operated in the accumulated charge regime, an ACS bias voltage (VACS) is applied to the ACS to remove or otherwise control the accumulated charge; wherein the VACS is sufficiently negative with respect to ground, the source, and the drain to cause removal of or otherwise control the accumulated charge.
