Abstract
An ESD protection circuit that includes a clamp path including two clamp transistors and a GIDL detection circuit for detecting GIDL current conditions in the ESD protection circuit. The GIDL detection circuit generates a signal indicative of a GIDL current condition. The signal is utilized to control a voltage of a control electrode of a clamp transistor of the clamp path to increase the conductivity of the clamp transistor when the signal is indicative of a GIDL current condition to minimize a GIDL current through at least through a portion of the clamp path when the second clamp transistor is nonconductive where no ESD current is being discharged through the clamp path.
