  • Patent number: 11619688
    Abstract: A planar Hall sensing element includes a first pair of sensing electrodes mutually opposed in a first direction across the sensing element and a second pair of sensing electrodes mutually opposed in a second direction across the sensing element, with the second direction orthogonal to the first direction. A first pair of bias electrodes is mutually opposed in a third direction and a second pair mutually opposed in a fourth direction across the sensing element, the fourth direction orthogonal to the third direction. The third and fourth directions are rotated 45° with respect to the first and second directions so each sensing electrode is arranged between a bias electrode of the first pair and second pair. A DC bias current is supplied between the first and second pairs of bias electrodes. First and second Hall voltages are sensed at the first and second pairs of sensing electrodes.

  • Patent number: 10571531
    Abstract: A Hall sensor may include a Hall sensing element configured to produce a Hall voltage indicative of a magnetic field when traversed by an electric current, and a first pair of bias electrodes mutually opposed in a first direction across the Hall sensing element. The Hall sensor may include a second pair of bias electrodes mutually opposed in a second direction across the Hall sensing element. The Hall sensor may include a first pair of sensing electrodes mutually opposed in a third direction across the Hall sensing element, and a second pair of sensing electrodes mutually opposed in a fourth direction across the Hall sensing element. The fourth direction may be orthogonal to the third direction, each sensing electrode being between a bias electrode of the first pair and a bias electrode of the second pair.
