Low voltage input level shifter circuit and method for utilizing same

According to one embodiment, a level shifter circuit operable with a low voltage input comprises first and second pull-down switches configured to receive the low voltage input as respective non-inverted and inverted control voltages, first and second pull-up switches coupled between the respective first and second pull-down switches and an output supply voltage, and a pull-up boost switching stage coupled to a node between the first pull-up switch and the first pull-down switch. The pull-up boost switching stage is configured to turn ON in response to the second pull-down switch turning ON, and to turn OFF before the first pull-up switch turns OFF. In one embodiment, the level shifter circuit may be implemented as part of an input/output (IO) pad of an integrated circuit (IC) fabricated on a semiconductor die.
