Abstract: A circuit including a voltage-controlled transistor to be switched. A first transistor is switched on, mediated by a control signal, and a first current flows through a series circuit and starts to subject a control input of the voltage-controlled transistor to charge reversal. The first current brings about a first potential shift at a connecting node. A second transistor is switched on by this first potential shift and a second current therefore flows through the switching path of the second transistor into the control input of the first transistor, which amplifies the first current. The increasing charge reversal of the control input of the voltage-controlled transistor brings about a second potential shift at the connecting node, the second transistor is switched off by this second potential shift, and the first transistor remains switched on, however, and holds the voltage-controlled transistor in its new switching state.
