Beschreibung
Zusammenfassung:	A sensor circuit for measuring a physical quantity including: a signal acquisition circuit having a sensor to provide an input signal related to the physical quantity; a processing circuit to receive the input signal and for providing an output signal representative of the physical quantity; the processing circuit comprising a closed loop comprising: a first sub-circuit arranged for receiving the input signal and a feedback signal, and configured for providing a first signal; a frequency dependent filter for receiving and filtering the first signal, and for providing the output signal; a second sub-circuit for receiving and converting the filtered signal into the feedback signal using a non-linear function.
