  • Sequential electrostatic discharge (ESD)-protection employing cascode NMOS triggered structure
    Patent number: 8810981
    Abstract: An Electrostatic Discharge (ESD) protection circuitry comprises a protection device structure. The protection device structure includes at least one transistor with a gate operably connected to a pad. The at least one transistor turns on upon an ESD event and conducting charge to a substrate. At least one additional transistor with a gate operably connected to the substrate turns on after the at least one transistor upon an ESD protection event.
    Type: Grant
