Abstract

A magnetic field sensing apparatus including a magnetic flux concentrator and a plurality of single direction magneto-resistive sensors is provided. The magnetic flux concentrator has a first and a second end portions opposite to each other. The single direction magneto-resistive sensors have the same pinning direction and are disposed beside the magnetic flux concentrator. The single direction magneto-resistive sensors further include a plurality of first and second single direction magneto-resistive sensors. The first single direction magneto-resistive sensors are disposed beside the first end portion and further include a first and a third portions respectively being disposed two opposite sides of the first end portion. The first and a third portions are coupled to a first full Wheatstone bridge. The second single direction magneto-resistive sensors are disposed beside the second end portion and further include a second and a fourth portions respectively being disposed two opposite sides of the second end portion. The second and the fourth portions are coupled to a second full Wheatstone bridge.
