Vertical hall sensor with integrated trace

An integrated circuit (IC) fabricated on a substrate that has a substrate surface, the IC comprising:

• a magnetic concentrator;
• a vertical Hall sensor configured to detect a magnetic field oriented in a first dimension parallel to the substrate surface, and located near the magnetic concentrator;
• and
• a trace, the trace having a first end, a second end, a first leg, and a second leg, the first leg and second leg each oriented in a second dimension that is perpendicular to the first dimension and is parallel to the substrate surface, the first leg coupled to the second leg in series between the first end and the second end, the first leg located near the magnetic concentrator and so that a line perpendicular to and intersecting the substrate surface and the magnetic concentrator intersects the first leg, and the second leg located near the vertical Hall sensor.
