SIGNAL PROCESSING ARRANGEMENT, SENSOR ARRANGEMENT AND SIGNAL PROCESSING METHOD

A signal processing arrangement (100) has a signal input (SI) for connecting a capacitive sensor (CS). An amplifier circuit (AMP) is coupled between the signal input (SI) and a feedback point (CB1). A loop filter (LF) is coupled downstream to the feedback point (CB1). A quantizer (QT) is connected downstream to the loop filter (LF) and provides a multi-bit output word (OW). The multi-bit output word (OW) consists of one or more higher significance bits (HSB) and one or more lower significance bits (LSB). A first feedback path (FB1) is coupled between a quantizer (QT) and the feedback point (CB1) for providing a first feedback signal to the feedback point (CB1) being representative of the one or more lower significance bits (LSB). A second feedback path is coupled to the quantizer (QT) for providing a second feedback signal to the signal input (SI) being representative of the one or more higher significance bits (HSB).
