Abstract
A Hall sensor on a semiconductor substrate includes a Hall plate in the semiconductor substrate, where the Hall plate includes a first zone having a first conduction type. The semiconductor substrate also include a second zone having a second conduction type. A space-charge zone in the semiconductor substrate separates the first zone and the second zone, first contacts supply a control current to the first zone, and second contacts supply a compensation current to the second zone.
