  • Diode structure to suppress parasitic current
    Patent number: 7466004
    Abstract: A diode conducts current between an anode terminal and a cathode terminal. The diode includes a parasitic transistor formed between one of the terminals and the substrate. The diode also includes a second transistor that competes with the parasitic transistor to direct current flow between the anode terminal and the cathode terminal.
    Type: Grant
