Abstract
A high voltage output stage amplifier that maximizes the output voltage swing when the peak-to-peak output voltage signal is higher than the supply voltage used in the signal conditioning circuits of the amplifier. The amplifier allows the maximum peak-to-peak swing on the output stage by shifting the quiescent voltage of the output stage to the midpoint of the output supply voltage. The shift is accomplished by tapping an offset current at the input of the error integrating stage of the amplifier proportional to the difference in the two power supply voltages.
