1. A device for correcting a sensor signal, comprising: a sensor interface configured to read in a sensor signal from a sensor configured to measure a physical variable; a signal processing unit formed by a first digital filter and a quantizer, the quantizer being connected downstream of the first digital filter, the signal processing unit being connected to an output of the sensor interface and configured to determine a processing signal by using the sensor signal; a feedback unit connected to an output of the signal processing unit and configured (i) to output a feedback signal to the sensor, and (ii) to provide the feedback signal to the sensor on the basis of a nonlinear processing rule and the processing signal; and a signal correction unit formed by second digital filter, the signal correction unit being connected to the output of the signal processing unit and configured (i) to determine a corrected signal based on the processing signal which is provided to the feedback unit, and (ii) to determine the corrected signal based on at least one of the nonlinear processing rule and a processing rule derived from the nonlinear processing rule, the signal correction unit being arranged downstream of the processing signal which is provided to the feedback unit.
