Abstract
A high speed voltage level shifter for use in circuitry having core circuits operating at a very low supply voltage includes a boost circuit for producing a boosted signal in accordance with a non-inverted input signal, and a voltage shifting stage for producing an output signal in response to an inverted input signal and the boosted signal. The boost circuit translates the boosted signal into a middle voltage level when the non-inverted input signal is at logic '0'. When the inverted input signal and the boosted signal are both at the logic '0', the voltage shifting stage provides the output signal with a high voltage level. Otherwise, the voltage shifting stage pulls down the output signal to ground when the boosted signal is at the middle voltage level and the inverted input signal is at a low voltage level equal to the very low supply voltage level.
