Abstract
Planar magnetic sensor, made in particular via CMOS techniques on a semiconductor substrate ( ) of for example parallelepiped shape. It includes an amorphous ferromagnetic core ( ) in the shape of a Greek cross which occupies the two diagonals of the square defined by the outer contour ( ) of the excitation coil ( ), the latter being made in the form of a planar winding of square shape. One thus measures, via flat detection coils ( and ) which are mounted in series and in a differential arrangement, the two orthogonal components (H H ) of the external magnetic field (Hext).
