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.
