Zusammenfassung:	A Sensor arrangement is provided, comprising a first capacitive sensor (1) and a second capacitive sensor (2). A charge pump (3) is coupled to the first capacitive sensor and to the second capacitive sensor, the charge pump being operable to deliver a positive bias voltage. A differential output has a first terminal (OUTN) coupled to the first capacitive sensor and a second terminal (OUTP) coupled to the second capacitive sensor.
