  • Snapback clamps for ESD protection with voltage limited, centralized triggering scheme
    Patent number: 11056879
    Abstract: An apparatus for electrostatic discharge protection. In one embodiment, an integrated circuit (IC) includes a trigger circuit configured to generate a trigger voltage VT in response to an electrostatic discharge (ESD) event. A plurality of metal oxide semiconductor (MOS) transistors are coupled to the trigger circuit. The plurality of MOS transistors are configured to conduct ESD current from a plurality of circuit nodes, respectively, to a ground conductor in response to the trigger circuit generating the trigger voltage VT. A voltage limiter circuit is also included and is configured to limit the trigger voltage VT.
    Type: Grant
