Abstract
One embodiment features an electrical circuit comprising: a high-voltage input configured to receive a high voltage into the electrical circuit; a low-voltage input configured to receive a low voltage into the electrical circuit; a thin-oxide circuit comprising a thin-oxide metal-oxide-semiconductor field-effect transistor (MOSFET); and a protection circuit configured to protect the thin-oxide circuit from the high voltage, wherein the protection circuit comprises a thick-oxide MOSFET clamp circuit, and an adaptive voltage reference circuit configured to provide an adaptive reference voltage, wherein the thick-oxide MOSFET clamp circuit is biased by the adaptive reference voltage.
