Abstract: Signal processing circuit for a Hall sensor and signal processing method. Signal processing circuits for four-phase spinning Hall magnetic field sensors, corresponding methods and corresponding magnetic field sensor apparatuses are provided. In this case, a correction signal (c) is generated on the basis of a first feedback signal (fb1) and a second feedback signal (fb2), wherein the first feedback signal (fb1) is provided with a shorter signal propagation time than the second feedback signal (fb2).
