  • Mixed voltage tolerant input/output electrostatic discharge devices
    Patent number: 7825475
    Abstract: An input/output (I/O) mixed-voltage drive circuit and electrostatic discharge protection device for coupling to an I/O pad. The device includes an NFET device having a gate, a drain, a source and body, the gate adapted for coupling to a pre-drive circuit, the source and the body being coupled to one another and to ground. The device also includes a bipolar junction transistor having a collector, an emitter and a base, the emitter being coupled to the drain of the NFET and the collector being coupled to the I/O pad.
    Type: Grant

  • Silicon controlled rectifier electrostatic discharge protection device with external on-chip triggering and compact internal dimensions for fast triggering
    Patent number: 6791122
    Abstract: A silicon controlled rectifier electrostatic discharge protection circuit with external on-chip triggering and compact internal dimensions for fast triggering. The ESD protection circuit includes a silicon controlled rectifier (SCR) having an anode coupled to the protected circuitry and a cathode coupled to ground, where the cathode has at least one high-doped region. At least one trigger-tap is disposed proximate to the at least one high-doped region and an external on-chip triggering device is coupled to the trigger-tap and the protected circuitry.

  • Multifinger silicon controlled rectifier structure for electrostatic discharge protection
    Patent number: 6621126
    Abstract: An electrostatic discharge (ESD) protection circuit including a silicon controlled rectifier having a plurality of SCR fingers. Each SCR finger includes at least one interspersed high-doped first region formed within a first lightly doped region. At least one interspersed high-doped second region are formed within a second lightly doped region, where the first and second lightly doped regions are adjacent one another. At least one first trigger-tap is coupled to the second lightly doped region. Additionally, at least one first low-ohmic connection is respectively coupled between the at least one first trigger tap of each SCR finger.
