Abstract
A circuit arrangement for generating a supply voltage with a controllable ground potential level includes a voltage source that provides the supply voltage ungrounded, a control unit that generates an adjustable control d.c. voltage to ground, and an operational amplifier that is connected via its voltage supply terminals to the supply voltage source, where the control d.c. voltage is applied to the inverting input of the operational amplifier, the non-inverting input of the operational amplifier is connected via a resistor network to the voltage source and to a ground terminal and the output of the operational amplifier is fed back to the inverting input via a capacitor.
