Abstract
A Hall-effect element is connected at one Hall current terminal to ground and at the other Hall current terminal to a DC voltage application circuit. Two Hall voltage terminals of the Hall-effect element are coupled with the base and the emitter of a first transistor, respectively. A second transistor is connected in series to the first transistor in such a way that the collector of the second transistor is fed back in current mode to the emitter of the first transistor.
