Abstract
An inverter circuit () having a drive transistor () that operably couples to a voltage bias input () (and where that drive transistor controls the inverter circuit output by opening and closing a connection between the output () and ground ()) is further operably coupled to a feedback switch (). In a preferred approach the feedback switch is itself also operably coupled to the voltage bias input and the output and preferably serves, when the drive transistor is switched 'off,' to responsively couple the voltage bias input to the drive transistor in such a 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.
