    Abstract: A circuit includes a logic stage, an inverter stage, and a driver stage. The logic stage and the inverter stage are provided with current limiters, which include a D-mode feedback transistor and a component that generates a voltage drop. A feedback loop connects the source and the gate of the D-mode feedback transistor via this component. The driver stage includes E-mode transistors connected in a totem pole that drive a D-mode transistor and an E-mode transistor to connect and disconnect the load circuit.

    Abstract: A current-limited differential entry stage compares an input signal to a reference voltage generated by a current-limited transistor or diode configuration. Current limiters comprise a D-mode feedback transistor having a gate-source junction. The D-mode transistor is not conducting between the source and the drain if a gate-source voltage is more negative than a negative threshold voltage, and conducting between the source and the drain, otherwise a feedback connection connects the source of the D-mode feedback transistor to its gate via a component that generates a voltage drop.
