INTEGRATED SILICON CONTROLLED RECTIFIER (SCR) AND A LOW LEAKAGE SCR SUPPLY CLAMP FOR ELECTROSTATIC DISCHARGE (ESD) PROTECTION

摘要

Electrostatic discharge (ESD) protection is provided in using a supply clamp circuit using an ESD event actuated SCR device. The SCR device may include an embedded field effect transistor (FET) having an insulated gate that receives a trigger signal from an ESD detection circuit. The SCR device may alternatively include a variable substrate resistor having an insulated gate that receives a trigger signal from an ESD detection circuit.
