Abstract
A level shifter and method are disclosed. In one embodiment, the level shifter includes a DC biasing component connected with both an AC coupling component and a high voltage output amplifier. The AC coupling component receives an input signal from a low voltage domain and output a first voltage signal. The DC biasing component is configured to bias the first voltage signal using a bias voltage based on a previous output signal in a high voltage domain. The high voltage output amplifier is configured to amplify the DC biased voltage signal in the high voltage domain and provide an output signal in the high voltage domain.
