Abstract: An amplifier circuit includes an amplifier unit that is configured to receive an input signal and generate a switching output signal. A level shifter is configured to shift the amplitude of the input signal to have a shifted amplitude that is proportional to a peak-to-peak amplitude of the switching output signal.
