Abstract
A magnetic sensor includes a first bridge circuit including a plurality of magnetic field sensor elements, each configured to generate a sensor signal in response to the magnetic field impinging thereon. The first bridge circuit is configured to generate a first differential signal based on sensor signals generated by the plurality of magnetic field sensor elements. The plurality of magnetic field sensor elements include a first, second, and third pair of sensor elements. The first pair are arranged at center region of the magnetic sensor, the second pair are arranged at a first side region of the magnetic sensor and are displaced a first distance from the first pair, and the third pair are arranged at a second side region of the magnetic sensor, opposite to the first side region, and are displaced a second distance from the first pair that is substantially equal to the first distance.
