Classification: CPC G  H | IPC G  H

Claim 0:
1. A current sensor, comprising:
a substrate comprising a first layer and a second layer, wherein the substrate includes a path for at least one current-carrying conductor;
a first plurality of measurement conductors formed on the first layer;
a second plurality of measurement conductors formed on the second layer; and
a first plurality of vias, formed in the substrate, arranged to connect the ends of the first plurality of measurement conductors with respective ends of the second plurality of measurement conductors, so as to form a first current measurement coil which progresses around the path in a first circumferential direction and a second current measurement coil which progresses around the path in a second circumferential direction,
wherein each measurement conductor of the first plurality of measurement conductors is aligned with a respective measurement conductor of the second plurality of measurement conductors in a radial plane that is perpendicular to a surface of the substrate.
