Abstract: This disclosure is directed to a circuit that includes a substrate, a target device on the substrate, and an electrostatic discharge (ESD) device electrically coupled to the target device. The ESD device includes an ESD detection circuit electrically coupled to a first reference voltage supply and a second reference voltage supply, an inverter circuit electrically coupled to the ESD detection circuit and configured to trigger in response to an ESD event on the first or second reference voltage supply, a rectifier circuit electrically coupled to the inverter circuit and configured to rectify a current discharged from the inverter circuit, and a transistor electrically coupled to the rectifier circuit and configured to discharge a remaining current passing through the rectifier circuit.
