Abstract
An early triggered MOSFET ESD protection circuit based on reduction of the trigger voltage is described. A transient negative voltage is generated and applied to a gate of a MOSFET during a positive ESD event. The instant invention improves ESD performance, and is particularly useful for thin gate oxide of 40 Å and less.
