DEVICE COMPRISING A MAGNETO RESISTIVE SYSTEM

摘要

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 (26b,26c,27b,27c) coupled to the first/second magneto resistive elements (26a,27a) such that first/second currents flowing through these first/second magneto resistive elements (26a-26c,27a-27c) 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 (36a-36c,37a-37c) comprise different first sizes such as alternating first/second widths.
