Patent ID: 7550998

Claim:
An inverter circuit comprising: a voltage bias input; a drive transistor operably coupled to the voltage bias input wherein the drive transistor controls an inverter circuit output by opening and closing a connection between the output and ground and wherein the drive transistor further comprises a drain and a source electrode that is intentionally larger than a gate terminal of the drive transistor in a channel width direction to provide electrode portions that extend beyond the gate terminal, wherein the electrode portions introduce parallel leakage across the transistor channel and thereby increase “off” current to thereby improve switching speed stability; a feedback switch operably coupled to the voltage bias input, the output, and the drive transistor, wherein when the drive transistor is switched “off” the feedback switch responsively couples the voltage bias input to the drive transistor in such as way as to cause a gate terminal of the drive transistor to have its polarity relative to a source terminal of the drive transistor reversed and hence permit the inverter circuit to operate across a substantially full potential operating range of the drive transistor.
