  • Low voltage NMOS-based electrostatic discharge clamp
    Publication number: 20040155300
    Abstract: Systems and methods are described for a low-voltage electrostatic discharge clamp. A resistor pwell-tied transistor may be used as a low-voltage ESD clamp, where the body of the transistor is coupled to the source by a resistor, thereby reducing a DC leakage current and minimizing latch-ups in the transistor while maintaining effective ESD performance.
