Abstract :
We present a new magnetic sensor based on the Hall effect, sensitive to a cylindrical magnetic field. Such a field is found around a wire carrying a current or under the gap between magnetic concentrators. Compared to traditional (plate-like) Hall devices, the geometry of the cylindrical Hall device allows lower bias voltage and lower offset to be achieved. The combination of this new device with integrated magnetic concentrators results in a very high detectivity magnetic sensor.
