  • Low voltage NMOS-based electrostatic discharge clamp
    Patent number: 7288820
    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.
    Type: Grant
    Filed: December 1, 2004
    Date of Patent: October 30, 2007
    Assignee: Freescale Semiconductor, Inc.
    Inventors: Michael Baird, Richard T. Ida, James D. Whitfield, Hongzhong Xu, Sopan Joshi
