1. A bridge comprising:
a first set of sub-arrays forming a first magnetoresistance element, each sub-array of the first set having a first reference direction;
a second set of sub-arrays forming a second magnetoresistance element, each sub-array of the second set having a second reference direction different from the first reference direction;
a third set of sub-arrays forming a third magnetoresistance element, each sub-array of the third set having a third reference direction;
a fourth set of sub-arrays forming a fourth magnetoresistance element, each sub-array of the fourth set having a fourth reference direction different from the third reference direction;
a fifth set of sub-arrays forming a fifth magnetoresistance element, each sub-array of the fifth set having a fifth reference direction;
a sixth set of sub-arrays forming a sixth magnetoresistance element, each sub-array of the sixth set having a sixth reference direction different from the fifth reference direction;
a seventh set of sub-arrays forming a seventh magnetoresistance element, each sub-array of the seventh set having a seventh reference direction; and
an eighth set of sub-arrays forming an eighth magnetoresistance element, each sub-array of the eighth set having an eighth reference direction different from the seventh reference direction,
wherein the first, the second, the third, the fourth, the fifth, the sixth, the seventh and the eighth sets of sub-arrays are arranged in a matrix on a die.
