Abstract:
1. An integrated device for measuring magnetic fields comprising: a first sensor unit and a second sensor unit fanned in a common plane on a single substrate, said first sensor unit and said second sensor unit comprising magnetoresistive material; said first sensor unit having a first output and said second sensor unit having a second output; said first sensor unit comprising at least one sensing element having a total anisotropy field in a first direction; said second sensor unit comprising at least one sensing element having a total anisotropy field in a second direction with said second direction being substantially perpendicular to said first direction; a conductor located in a plane spaced from said common plane for setting a direction of magnetization in at least a portion of said at least one sensing element of said first sensor unit in said first direction and setting a direction of magnetization in at least a portion of said at least one sensing element of said second sensor unit in said second direction; and wherein said first output is representative of magnetic field components perpendicular to said first direction and said second output is representative of magnetic field components perpendicular to said second direction.
