Abstract

One example of the invention relates to a circuit arrangement for actuating a high-side transistor which includes a control terminal and a load terminal. The circuit arrangement includes a driver circuit that is designed to generate, in response to a control signal, a driver signal for the control terminal of the high-side transistor. A supply circuit is capacitively coupled to a radio-frequency signal source and is designed to provide a supply voltage to the driver circuit, the supply voltage being referenced to a floating reference potential.
