ABSTRACT:
A circuit for shifting a signal from a first voltage level to a second voltage level. In one embodiment, a voltage translator circuit has first and second transistors that are cross-coupled; a third transistor having a gate coupled with the input signal, the third transistor being coupled between the gate of the second cross-coupled transistor and the drain of the first cross-coupled transistor; and a fourth transistor having a gate coupled with an inverted version of the input signal, the fourth transistor being coupled between the gate of the first cross-coupled transistor and the drain of the second cross-coupled transistor. In another embodiment, the circuit may have, as part of its output stage, a first and second output transistors connected in series, and a third output transistor coupled between the second output transistor and ground, the third output transistor having a gate coupled with a high voltage supply.
