Abstract
A voltage domain crossing circuit and method are disclosed. In one embodiment, the voltage domain crossing circuit comprises an AC coupling component, a DC biasing component and a high voltage output amplifier. The AC coupling component receives an input low voltage signal and AC couples and splits the signal into two voltages. The two voltages are then DC biased to a predetermined bias voltage using the DC biasing component. The high voltage output amplifier then amplifies the biased voltages in the high voltage domain yielding a signal in the high voltage domain. Other embodiments of the voltage domain crossing circuit and method are also disclosed.
