Voltage compensated level-shifter

A method comprising:

• receiving an input signal for level shifting from a first power supply level to a second power supply level;
• generating a first inverted signal by inverting the input signal, the first inverted signal having a logical high level of the first power supply level;
• generating a second inverted signal by inverting the input signal, the second inverted signal having a logical high level of the second power supply level;
• and
• applying a logical NOR operation to inputs comprising the first and second inverted signals, the logical NOR operation to generate an output signal which is level shifted to the second power supply level.

A system comprising:

• a display unit;
• a processor coupled to the display unit, the processor including a level shifter comprising:
• a first inverter to receive an input signal for level shifting from a first power supply level to a second power supply level, and to generate a first inverted signal, the first inverter operating on the first power supply level;
• a second inverter to receive the input signal and to generate a second inverted signal, the second inverter operating on the second power supply level;
• and
• a NOR logical gate to receive the first and second inverted signals and to generate an output signal, the NOR logical gate operating on the second power supply level, wherein the output signal is level shifted to the second power supply level;
• and
• a wireless interface for allowing the processor to communicate with another device.
