Abstract

A level shifter includes an output stage transistor and a level controller. The level controller receives a selection signal and provides a reference voltage at a gate terminal of the output stage transistor based on the selection signal. The output stage transistor, on being enabled by the reference voltage, provides a first level shifted output based on a first output reference voltage.
