ABSTRACT:
A High Voltage Regulation apparatus which uses an amplifier having an arbitrarily large number of stacked MOSFETs to provide low impedance shunt regulation with a "domino effect". Voltages of many kilovolts can be conveniently regulated. voltage sharing among the devices is assured by the domino arrangement. External capacitances are added to optimize low impedance voltage regulation, including an external capacitor connected between the drain and gate of each stage to equalize the drain to gate and gate to source capacitances. There may also be an external capacitor connected between the drain and source of each stage to provide low amplifier impedance at high frequency, or a lumped external capacitor connected across the entire amplifier string, to provide low amplifier impedance at high frequency. The amplifier uses a unity-gain inverting amplifier as its basic building block. N-number of these building blocks are stacked to accommodate whatever voltage stand-off level is desired.
