  • Electrostatic discharge protection structures for high speed technologies with mixed and ultra-low voltage supplies
    Publication number: 20050057866
    Abstract: An electrostatic discharge (ESD) protection circuit in a semiconductor integrated circuit (IC) having protected circuitry. In one embodiment, the ESD protection circuit includes a pad adapted for connection to a first voltage source of a protected circuit node of the IC, and a silicon controlled rectifier (SCR) having an anode adapted for coupling to the first voltage source, and a cathode adapted for coupling to a second voltage source. At least one capacitive turn-on device respectively coupled between at least one of a first gate of the SCR and the first voltage source, and a second gate of the SCR and the second voltage source.
