ABSTRACT:
A level shifter is presented that allows fast switching while requiring low power. In accordance with some embodiments of the invention, the level shifter is a two stage level shifting circuit with p-channel and n-channel transistors biased so as to limit the potential between the source to gate or drain to gate of any of the transistors. Pull-up transistors are placed in a transition state so that spikes resulting from an increasing or decreasing input voltage turn on or off the pull up transistors to assist in the switching.
