1. A device for correcting a sensor signal, comprising: a sensor interface configured to read in a sensor signal which represents a physical variable; a signal processing unit configured to determine a processing signal by using the sensor signal; a feedback unit configured (i) to output a feedback signal to the sensor, and (ii) to provide the feedback signal on the basis of a nonlinear processing rule and the processing signal; and a signal correction unit configured (i) to determine a corrected signal by using the processing signal, and (ii) to determine the corrected signal by using the nonlinear processing rule or a processing rule derived from the nonlinear processing rule.
