  • Resistorless electrostatic discharge protection device for high speed integrated circuits
    Patent number: 4996626
    Abstract: An electrostatic discharge protection circuit without the use of a series resistor is described. MOSFET transistors with a turn-on voltage above the postive supply voltage but below the breakdown voltage are used. In one embodiment, parasitic bipolar transistors formed in conjunction with the MOSFETs are employed for further protection.
