  • MOS switch with hysteresis
    Patent number: 4097772
    Abstract: An MOS circuit possessing hysteresis and positive feedback for fast switching includes a first MOSFET having its gate connected to an input. A second depletion mode MOSFET has its drain connected to the source of the first MOSFET and its source connected to ground. A third depletion mode MOSFET has its drain connected to the source of the first MOSFET and its gate and source connected to the drain of a fourth MOSFET and to the gate of a fifth MOSFET. The gate of the fourth MOSFET is connected to the gate and source of a sixth depletion mode MOSFET and to the drain of the fifth MOSFET. The fifth MOSFET has its source connected to ground.
