Abstract
A method and apparatus for providing ESD event protection for a circuit using a source or bulk pump to increase the bulk and/or source potential level during an ESD event. The apparatus comprises a protection circuit that, in response to an ESD event, limits the voltage formed between two terminals of a transistor by adjusting a potential level on the second terminal.
