Abstract:
A magnetic field sensing apparatus including a magnetic flux concentrator, a plurality of magnetoresistance units, and a plurality of magnetization direction setting elements is provided. The magnetic flux concentrator has a top surface, a bottom surface opposite to the top surface, and a plurality of side surfaces connecting the top surface and the bottom surface. The magnetoresistance units are respectively disposed beside the side surfaces. The magnetoresistance units are electrically connected to form an unchangeable Wheatstone full bridge. The magnetization direction setting elements set the magnetization directions of the magnetoresistance units into three different combinations in three different periods, respectively, so as to enable the unchangeable Wheatstone full bridge to respectively measure the magnetic field components in the three different directions in the three different periods.

Claim (Index 20):
A magnetic field sensing apparatus, comprising:\n a magnetic flux concentrator, having a top surface, a bottom surface opposite to the top surface, and four side surfaces connecting the top surface and the bottom surface; at least four magnetoresistance units, respectively disposed beside the four side surfaces, wherein the at least four magnetoresistance units are electrically connected into two different combinations to form two kinds of Wheatstone full bridges in two different periods, respectively, so as to measure magnetic field components in two different directions and to cause the two kinds of the Wheatstone full bridges to respectively output two signals corresponding to the magnetic field components in the two different directions, wherein in any one of the two different periods, the number of the Wheatstone full bridge formed by electrically connecting the at least four magnetoresistance units is one; and a switching circuit, electrically connected to the at least four magnetoresistance units, wherein the switching circuit electrically connects the at least four magnetoresistance units into the two different combinations to form the two kinds of Wheatstone full bridges, respectively, and the two kinds of Wheatstone full bridges respectively measure the magnetic field components at the two different directions and respectively output the two signals corresponding to the magnetic field components in the two different directions.
