    • 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.
    • 包括要切换的压控晶体管的电路。 第一晶体管导通,由控制信号介导,并且第一电流流过串联电路,并开始使压控晶体管的控制输入受到反相充电。 第一个电流在连接节点上引起了第一个潜在的移位。 第二晶体管通过该第一电位移动导通,因此第二电流通过第二晶体管的开关路径流入第一晶体管的控制输入端,该第一晶体管放大第一电流。 电压控制晶体管的控制输入的增加的电荷反转在连接节点引起第二电位移动,第二晶体管被关断第二电位移动,并且第一晶体管保持接通,然而, 压控晶体管处于新的开关状态。
