Abstract
A transient detection circuit which may be used in an electrostatic discharge (ESD) clamp circuit. The transient detection circuit includes a filter circuit and an inverter circuit. The voltage switch point of the inverter circuit has a constant voltage offset from one of the nodes. When a filtered voltage level from the filter circuit crosses the voltage switch point of the inverter circuit (indicative of an ESD event), the inverter circuit provides a signal indicating an ESD event.
