Hall sensor insensitive to external magnetic fields

A method for manufacturing a Hall sensor, the method comprising:

• providing a first Hall element pair configured to provide a first measurement signal;
• providing a second Hall element pair configured to provide a second measurement signal;
• providing a third Hall element pair configured to provide a third measurement signal;
• disposing each Hall element of the third Hall element pair between Hall elements of the first Hall element pair and Hall elements of the second Hall element pair;
• and
• providing a measuring device connected to the first Hall element pair, the second Hall element pair, and the third Hall element pair, the measuring device being configured to (i) simultaneously receive the first measurement signal, the second measurement signal, and the third measurement signal and (ii) combine the first measurement signal, the second measurement signal, and the third measurement signal to form the total measurement signal using a calculation that takes into account positions of the first Hall element pair, the second Hall element pair, and the third Hall element pair, such that an error in the resulting total measurement signal caused by an external magnetic field is minimized.

A method of using a Hall sensor, the method comprising:

• activating a first Hall element pair to produce a first measurement signal;
• activating a second Hall element pair to produce a second measurement signal;
• activating a third Hall element pair to produce a third measurement signal, wherein Hall elements of the third Hall element pair are disposed between Hall elements of the first Hall element pair and Hall elements of the second Hall element pair;
• simultaneously receiving the first measurement signal, the second measurement signal, and the third measurement signal with a measuring device connected to the first Hall element pair, the second Hall element pair, and the third Hall element pair;
• and
• combining, with the measuring device, the first measurement signal, the second measurement signal, and the third measurement signal to form the total measurement signal using a calculation that takes into account positions of the first Hall element pair, the second Hall element pair, and the third Hall element pair, such that an error in the resulting total measurement signal caused by an external magnetic field is minimized.
