Abstract
Disclosed is a magnetometer architecture that uses a separate shield to minimize cross-axis sensitivity with low impact on main axis sensitivity. In an embodiment, a magnetometer with cross-axis shielding comprises: a ring shield; a magnetic yoke disposed within the ring shield; and one or more magnetic field sensors disposed between the ring shield and the magnetic yoke, the magnetic field sensors positioned relative to the ring shield and the magnetic yoke such that flux induced by a magnetic field is absorbed in a cross-axis direction of the magnetometer.
