  • Electrostatic discharge clamp with reduced off-state power consumption
    Patent number: 10985156
    Abstract: The present disclosure relates to an electrostatic discharge (ESD) clamp and, more particularly, to an ESD clamp with reduced off-state power consumption. The structure includes: one or more inverters connected to a timing circuit; a first transistor receiving an output signal from a last of the one or more inverters and an output signal from the timing circuit; a second transistor with its gate connected to the first transistor, in series; and a voltage node providing a separate voltage to a gate of the second transistor.
    Type: Grant
    Filed: January 10, 2018

  • PROGRAMMING AN ELECTRICAL FUSE WITH A SILICON-CONTROLLED RECTIFIER
    Publication number: 20160118138
    Abstract: Circuits for programming an electrical fuse, methods for programming an electrical fuse, and methods for designing a silicon-controlled rectifier for use in programming an electrical fuse. A programming current for the electrical fuse is directed through the electrical fuse and the silicon-controlled rectifier. Upon reaching a programmed resistance value for the electrical fuse, the silicon-controlled rectifier switches from a low-impedance state to a high-impedance state that interrupts the programming current.
