Abstract
A circuit, which includes a high voltage driver, is disclosed. The high voltage driver includes a P-type field effect transistor (PFET) and a source bias circuit. The source bias circuit receives a low voltage input signal and applies a direct current (DC) bias to the low voltage input signal to provide a DC biased signal. The PFET has a first source, a first gate, and a first drain. The first source receives the DC biased signal. The first gate receives a first low voltage DC supply signal. The first drain provides a high voltage output signal based on the DC biased signal and the first low voltage DC supply signal. In this regard, the high voltage driver receives and translates the low voltage input signal to provide the high voltage output signal.
