ABSTRACT:
An improved gate oxide protected level shifter is provided which has a higher speed of operation than is traditionally available. The level shifter includes a first capacitor coupled between a first output terminal and the input of an inverter and a second capacitor coupled between a first node and the output of the inverter. As a result, the speed of the transitions at the gates of the pair of cross-coupled P-channel MOS transistors is increased several times.
