Abstract:
1. Method for measuring an entity of a magnetic field using a Hall sensor, which is provided with at least one Hall plate which includes a group of two pairs ((A 1 , A 2 ), (B 1 , B 2 )) of terminals (A 1 , A 2 , D 1 , B 2 ) located at a distance from one another, an excitation signal being supplied from a source to one pair of terminals, and a detection signal, which forms a representation of the entity, being tapped off from the other pair of terminals by a processing circuit, wherein the source is a voltage source of which an impedance is negligible for use of the sensor, and the processing circuit has a negligible input impedance for tapping off the detection signal as a short-circuit current.
