Stray field suppression in magnetic sensor Wheatstone bridges
Abstract:
A magnetic sensor includes a 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, where the bridge circuit is configured to generate a differential signal based on sensor signals generated by the plurality of magnetic field sensor elements. The bridge circuit further includes a plurality of resistors, where at least one resistor of the plurality of resistors is coupled in parallel to each of the plurality of magnetic field sensor elements.
