Abstract
Magnetic sensors, sensor modules, and methods thereof are provided. A magnetic sensor includes a sensor arrangement including a plurality of magnetic field sensor elements electrically arranged in an asymmetrical bridge circuit, where a first total resistance of a first pair of sensor elements provided on a first side of the asymmetrical bridge circuit is different from a second total resistance of a second pair of sensor elements provided on a second side of the asymmetrical bridge circuit, and the asymmetrical bridge circuit is configured to generate a differential signal based on sensor signals generated by the plurality of magnetic field sensor elements in response to a magnetic field impinging thereon.
