  • Hall sensor insensitive to external magnetic fields
    Patent number: 9851221
    Abstract: A Hall sensor includes a first Hall element pair configured to provide a first measurement signal, a second Hall element pair configured to provide a second measurement signal, and a third Hall element pair configured to provide a third measurement signal. Each element in the third Hall element pair is arranged between Hall elements of the first Hall element pair and Hall elements of the second Hall element pair. The Hall element pairs are configured to be actuated such that the first, second, and third measurement signals can be combined into one aggregate measurement signal which corrects an error in an angle of rotation determination caused by an external magnetic field.
