Abstract:
1. A sensor, comprising: a first sensor unit, on an integrated circuit substrate, having a resistor bridge including a plurality of magnetoresistors, each magnetoresistor having at least one elongated strip of anisotropic magnetoresistive material having a longitudinal axis substantially parallel to a technological anisotropy axis of the magnetoresistive material; a second sensor unit, on the integrated circuit substrate, having a resistor bridge including a plurality of magnetoresistors having a plurality of elongated strips of the anisotropic magnetoresistive material, wherein the plurality of strips of the second sensor unit include: at least one conductive coil configured to selectively generate a plurality of different magnetic fields in the plurality of magnetoresistors of the second sensor unit to selectively set a magnetization of the plurality of magnetoresistors of the second sensor unit to different directions.
