Abstract
In a circuit designed to output a varying output voltage, the substrate of the semi-conductor component is connected to a regulator, in particular a switch, connected to a lower potential than the potential of the substrate of the circuit. The circuit can for example be used in a Subscriber Line Interface Circuit (SLIC).
