摘要: A magnetic field sensor comprises a substrate (13), an array (3) of magnetic field sensing elements (4) supported on the substrate, each magnetic field sensing element capable of measuring a minimum measurable magnetic field at a given frequency and means (5, 7) for processing signals from the magnetic field sensing elements to produce an output signal such that the magnetic field sensor is capable of measuring a magnetic field at the given frequency which is lower than the minimum measurable magnetic field for an element.
