Biasing arrangement, electronic apparatus, biasing method, and computer program

A biasing method for an electronic apparatus having an input device connected by wires, the method comprising

• generating a bias signal comprising a bias voltage and a reference voltage;
• controlling a flying capacitor circuitry having a first set of switches connected to said bias signal to selectively connecting and disconnecting the bias voltage and reference voltage, respectively, over a capacitor of the flying capacitor circuitry, and the flying capacitor circuitry further having a second set of switches to selectively connecting and disconnecting the voltage over the capacitor to an output of the flying capacitor circuitry connected to a wired connection between output of the flying capacitor circuitry and the input device of the apparatus, wherein the controlling comprises alternatingly opening the first set of switches and closing the second set of switches, and opening the second set of switches and closing the second set of switches such that the first and second sets of switches are not both in a connecting state at any time.
