ABSTRACT:
A voltage level translator boosts the gate voltage of a transistor, and increases the gate to source voltage, to allow operation over a wider range of supply voltages. The P/N ratio of transistors in the voltage level translator is therefore increased, and control of the flipping of nodes is dependent on gate voltages as opposed to P/N ratios.
