Patent ID: 7890891

Claim:
A circuit, comprising: a) a semiconductor-on-insulator (SOI) metal-oxide-silicon field effect transistor (MOSFET) having improved gate oxide reliability, wherein the SOI MOSFET is implemented so that it is adapted to have a specified value of a reliability property of a gate oxide of the SOI MOSFET, wherein the implementation of the MOSFET is responsive to a first value of a reliability property of the gate oxide having an uncontrolled accumulated charge proximate the gate oxide and wherein the implementation of the MOSFET is further responsive to a second value of the reliability property of the gate oxide having a controlled accumulated charge proximate the gate oxide; and b) a means for accumulated charge control (ACC) operatively coupled to the SOI MOSFET; wherein the reliability property of the gate oxide comprises a maximum electric field present in the gate oxide, and wherein the specified value of the reliability property comprises an electric field value E tb corresponding to a selected average time-to-breakdown for the gate oxide, and wherein the SOI MOSFET is adapted to have the specified value of the reliability property of the gate oxide by applying a second limiting gate bias voltage V g2 to a gate of the SOI MOSFET, wherein the second limiting gate bias voltage V g2 has an absolute value that is greater than the absolute value of a first limiting gate bias voltage V g1 applied to the gate of the SOI MOSFET, and wherein the first limiting gate bias voltage V g1 corresponds to the SOI MOSFET having the specified value of the reliability property without the means for ACC operatively coupled to the SOI MOSFET.
