Devices ( 1 ) comprising magneto resistive systems ( 2 ) for detecting incoming magnetic fields and comprising first/second branches with first/second magneto resistive elements ( 21 - 22 ) having first/second resistance values depending on the incoming magnetic fields according to first/second response curves are provided with shifting means for shifting the first/second response curves of the first/second branches into first/second directions to get an adapted linear behavior. The shifting means comprise first/second structures of the first/second branches resulting in a first/second local fields at the first/second branches such that the first/second response curves of the first/second branches are shifted into the first/second directions. The first/second branches comprise further first/second magneto resistive elements ( 26 b ,26 c ,27 b ,27 c) coupled to the first/second magneto resistive elements ( 26 a ,27 a) such that first/second currents flowing through these first/second magneto resistive elements ( 26 a- 26 c ,27 a- 27 c) result in the first/second local fields at the first/second branches. The first/second structures comprise first/second meander structures ( 36,37 ) wherein first/second parts ( 36 a- 36 c ,37 a- 37 c) comprise different first sizes such as alternating first/second widths.
