Abstract
A multi-axis GMR or TGMR based magnetic field sensor system is disclosed. Preferably a three axis sensor system is provided for sensing magnetic flux along three mutually orthogonal axes, which can be used for magnetic compass or other magnetic field sensing applications. The sensing units are operative to sense X and Y axis magnetic flux signals in the device (XY) plane, while Z axis sensitivity is achieved by use of a continuous ring shaped or octagonal magnetic concentrator that is adapted to convert the Z axis magnetic flux signal into magnetic flux signals in the XY plane.
