Abstract
A magneto-resistive sensor for measuring a magnetic field based on an anisotropic magneto-resistive (AMR) effect or a gigantic magneto-resistive (GMR) effect comprises a substrate and a plurality of resistors that include first magneto-resistive layer strips arranged in form of a bridge circuit on the substrate. The plurality of resistors have a resistance value that depends on a magnetic field strength. At least one second layer strip is connected in series with the first magneto-resistive layer strips of at least one of the plurality of resistors. The first magneto-resistive layer strips have a resistance that depends on temperature according to a first positive temperature coefficient; and the at least one second layer strip has a resistance that depends on temperature according to a second temperature coefficient different from the first temperature coefficient, the second temperature coefficient being non-negative.
