Abstract: A circuit for sensing a current comprises a substrate having a first and a second major surface, the second major surface being opposite to the first major surface. At least one magnetic field sensing element is arranged on the first major surface of the substrate and is suitable for sensing a magnetic field caused by a current flow in a current conductor coupled to the second major surface. The substrate also comprises at least one insulation layer, substantially buried between the first major surface and the second major surface of the substrate.
