  • Patent number: 6064202
    Abstract: The method serves for dynamically compensating the offset voltage of a Hall device. The Hall device can have either a platelike structure with at least two contact pairs, or any other arrangement deriveable by conformal mapping. The contact pairs are angled by e.g. 90.degree.. Each pair is supplied with a periodically alternating current whereby the phase shift of the supply currents corresponds to the spatial phase shift of the contact pairs and is e.g. 90.degree.. Superposition of the supplied currents results in a continuously spinning current vector in the Hall device. By measuring simultaneously the voltages between corresponding terminals, a signal consisting of the Hall voltage and a periodic offset voltage can be isolated. The offset voltage is eliminated by averaging the signal over at least one period.
