ABSTRACT:
A level shifter includes an N-channel enhancement-mode field effect transistor (40), a P-channel depletion-mode field effect transistor (38), and a current mirror (42) coupled to the source of the enhancement-mode transistor and the drain of the depletion-mode transistor; wherein the gates of the transistors are coupled to an input terminal and the source of the enhancement-mode FET is coupled to an output terminal to provide a level shifted output signal.
