Abstract
A biasing arrangement for an electronic apparatus having an input device connected by wires is disclosed. The biasing arrangement comprises a bias signal generator arranged to provide a bias voltage and a reference voltage; a flying capacitor circuitry having a first set of switches connected to said bias signal generator 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, wherein the first and second sets of switches are not both in a connecting state at any time; and a wired connection between output of the flying capacitor circuitry and the input device of the apparatus. An electronic apparatus, a biasing method, and a computer program are also disclosed.
