Abstract / Hauptanspruch
In one embodiment a Capacitive sensing arrangement has a capacitive sensor (CapS) for providing a sensor signal (Sin), and a charge amplifier circuit comprising an input (In) which is connected to the capacitive sensor (CapS), a single-input amplifier (A1) with an amplifier input (Ina) and an output (Out) to provide an output voltage (Vout) as a function of the sensor signal (Sin), means (M) for providing a bias voltage (Vref) coupled between the input (In) an the amplifier input (Ina), and a feedback capacitor (CF) coupled between the output (Out) and the input (In). Furthermore, a method for capacitive sensing is defined.
