Abstract

In a first phase a first sensor signal, essentially comprising the current offset signal of the sensor, is applied to the input of an electronic circuit. The first sensor signal is fed to a first signal path and stored therein. In a second phase a second sensor signal, comprising the current offset signal and a time-dependent measured signal, is applied to the input and the stored first sensor signal is fed to the input by means of the first signal path, such that essentially the time dependent measured signal is fed by means of a second signal path coupled to the input.
