Abstract
An input receiver for stepping down a high-voltage domain input signal into a low-voltage-domain stepped-down signal includes a waveform chopper. The waveform chopper chops the high-voltage domain input signal into a first chopped signal and a second chopped signal. A high-voltage-domain receiver combines the first chopped signal and the second chopped signal into a high-voltage-domain combined signal. A step-down device converts the high-voltage-domain combined signal into a stepped-down low-voltage-domain signal.
