ABSTRACT:
The disclosed technology provides a method of and an apparatus for voltage level shifting. A voltage level shifter includes two level shifting circuits and a differential amplifier. The differential amplifier forms a feedback loop with one level shifting circuit. The feedback loop controls the level shifting operation of both level shifting circuits. The differential amplifier can operate to provide a control signal that causes a level-shifted signal in the feedback loop to match a target signal. The two level shifting circuits can perform their level shifting operation based on the control signal.
