Abstract:
1. An electrostatic discharge (ESD) protection circuit, comprising: a first terminal and a second terminal; a transistor shunt element operably coupled between the first terminal and the second terminal, the transistor shunt element to provide a discharge path between the first terminal and the second terminal for both a positive discharge event and a negative discharge event, wherein the transistor shunt element is an enhancement-mode compound semiconductor field effect transistor; a shut-off element operably coupled with the second terminal, the shut-off element capable of keeping the transistor shunt element turned-off; and a triggering element to provide a voltage to turn on the transistor shunt element, the triggering element including a plurality of diodes operably coupled in series between the first terminal and the shut-off element, wherein the ESD protection circuit is fabricated using a high electron mobility transistor (HEMT) technology.
