Abstract
A magnetic field sensor for detecting a direction of a magnetic field comprises an xMR sensor designed to produce an xMR sine signal and an xMR cosine signal based on the magnetic field, and an AMR sensor designed to produce an AMR sine signal and/or an AMR cosine signal based on the magnetic field. A processing circuit is designed to determine the direction of the magnetic field using the xMR sine signal, the xMR cosine signal, a first phase difference between the xMR sine signal and the AMR sine signal or the AMR cosine signal, and a second phase difference between the xMR cosine signal and the AMR sine signal or the AMR cosine signal.
