Abstract

A single supply level shifter circuit for shifting the voltage level of an input voltage includes a voltage translation stage and a driver stage. The voltage translation stage receives the input voltage and a voltage supply and generates a first voltage. When a magnitude of the input voltage is LOW, the first voltage is LOW. The first voltage is provided to the driver stage, which inverts the first voltage to generate an output voltage that is at a voltage supply (Vdd) level, thereby level shifting the input voltage.
