  • Method and apparatus for providing current controlled electrostatic discharge protection
    Patent number: 7110230
    Abstract: A method and apparatus for providing ESD protection. An ESD clamp is connected across the terminals to be protected circuit. The clamp is coupled to a current detector that activates the clamp when current from an ESD event exceeds a predefined limit.

  • Method and apparatus for protecting a gate oxide using source/bulk pumping
    Publication number: 20050231866
    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.
