Abstract: Systems and methods to detect when the external magnetic field becomes higher than the saturation field of AMR material are described. Approaches include saturation detection by combining sensors with different full-scale ranges, saturation detection using DC current and saturation detection by arranging sensitive axes at 45° offsets.
