We have designed and realized a new integrated Hall structure that converts the magnetic field vector in the chip plane, into an ac signal, whose amplitude and phase correspond to the magnitude and direction of the field. It is the first Hall sensor that provides the field angle without the need of computing an arctan function. The Hall structure is formed by a n-well ring with a large number of contacts equally distributed along the ring, like a circular railroad track. Each contact is… CONTINUE READING
