Abstract: The invention concerns an angle sensor and a method of measuring an angle of a magnetic field. The angle sensor is configured to measure a direction of a magnetic field in a plane, comprising a first magnetic field sensor having a first sensitivity direction and delivering a first voltage, a second magnetic field sensor having a second sensitivity direction and delivering a second voltage, a first current source supplying a first biasing current to the first magnetic field sensor, a second current source supplying a second biasing current to the second magnetic field sensor (2), and electronic circuitry configured to adjust the first biasing current and the second biasing current in such a manner that a sum of the first voltage and the second voltage equals 0.

Abstract: A vertical Hall device has a deep N-well, two inner contacts, two outer contacts and, optionally, a central contact disposed at a surface of the deep N-well and arranged along a straight symmetry line. The vertical Hall device is designed according to the invention to have an effective width of the outer contacts that is bigger than an effective width of the inner contacts. A shallow highly doped P+ stripe may be disposed between the inner contacts or between each of the inner contacts and the central contact. These measures help to balance the resistances of the Wheatstone bridge which describes the electrical characteristics of the vertical Hall device.

Abstract: The invention concerns a current transducer for measuring a current flowing through a cable, comprising at least one magnetic field sensor and an electronic circuit. The current transducer comprises a head with a ferromagnetic core optimized to reduce the effects of external magnetic fields. The invention further concerns a magnetic transducer comprising a magnetic field sensor and an electronic circuit. The electronic circuit comprises at least one current source, a transformer, a fully differential preamplifier coupled to the transformer, a phase sensitive detector coupled to the preamplifier and a logic block configured to operate the magnetic field sensor(s) to provide an AC output voltage. The magnetic field sensor(s) is preferably either a Hall element or an AMR sensor or a flux-gate sensor.
