Abstract
A method can use a current sensor that can include a magnetic flux concentrator along with first and second magnetic field sensing elements disposed proximate to the magnetic flux concentrator, wherein the magnetic flux concentrator is operable to influence a direction of first and second magnetic fields at the first and second magnetic field sensing elements, respectively, the first and second magnetic fields resulting from an electrical current passing through a conductor, the first and second magnetic field sensing elements operable to generate first and second signals, respectively, in response to the first and second magnetic fields, respectively, wherein the current sensor can also include a differencing circuit operable to subtract the first and second signals to generate a difference signal related to the electrical current.
