Abstract
An integrated fluxgate device has a magnetic core disposed over a semiconductor substrate. A first winding is disposed in a first metallization level above and a second metallization level below the magnetic core, and is configured to generate a first magnetic field in the magnetic core. A second winding is disposed in the first and second metallization levels and is configured to generate a second magnetic field in the magnetic core. A third winding is disposed in the first and second metallization levels and is configured to sense a magnetic field in the magnetic core that is the net of the first and second magnetic fields.
