  • APPARATUS AND METHOD FOR CONTROLLING LEAKAGE CURRENT IN BIPOLAR ESD CLAMPING DEVICES
    Publication number: 20060187595
    Abstract: An apparatus for controlling leakage current in an electrostatic discharge (ESD) clamping network of an integrated circuit includes a bipolar ESD protection circuit having a trigger device and at least one discharge device. A leakage disablement network is coupled to the ESD protection circuit, wherein the leakage disablement network is configured to limit leakage current through one or more of the trigger device and the at least one discharge device, in the absence of an ESD event.
