Abstract

A sensor, comprising: a conductor having a curved portion; a first anchor magnetic field sensing element that is formed at an intersection of a first axis and a second axis that is substantially perpendicular to the first axis, the first magnetic field sensing element being formed on a space that is partially enclosed by the curved portion; a first magnetic field sensing element that is formed on the first axis, the first magnetic field sensing element being disposed on an opposite side of the conductor from the first anchor magnetic field sensing element; and a second magnetic field sensing element that is formed on the second axis, the second magnetic field sensing element being disposed on an opposite side of the conductor from the first anchor magnetic field sensing element.
