Michele Biondi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Hall sensor, corresponding devices and method
    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.
