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.

Thin-oxide device protection circuits for data converters

A switch regulator module includes a switch and a current sensing module. The switch has an input port and an output port. The current sensing module senses a first voltage at the input port of the switch and a second voltage at the output port of the switch. The current sensing module generates a sense signal that is proportional to a current that flows through the switch based on the first and second voltages.
