MAGNETIC FIELD SENSOR AND ELEMENTARY MODULE COMPRISING THE SAME

摘要

The invention relates to a magnetic field sensor comprising: a transducer (60) for transforming a magnetic field to be measured into an electrical variable, a reaction field winding (68) for bringing an outer magnetic field closer to a reference value, a linear integrated amplifier (62) for amplifying the electrical variable, and a main counter-reaction loop (64) having two ends, one of said ends being connected to an output (94) of the amplifier, and the other end being connected to the reaction field winding.
