Abstract:
A die for a two dimensional position sensor, comprising:a first magnetosensitive sensor comprising a first pair of diametrically disposed magnetosensitive elements; anda second magnetosensitive sensor comprising a second pair of diametrically disposed magnetosensitive elements, wherein said first and second pairs of magnetosensitive elements are mutually orthogonally oriented and mutually interdigitated such that said first pair of magnetoresistive elements is electrically independent of said second pair of magnetosensitive elements, and wherein said first and second magnetosensitive elements are substantially equally magnetically biased;wherein said first magnetosensitive sensor senses movement of a magnetic material target along a first axis, and wherein said second magnetosensitive sensor senses movement of a magnetic material target along a second axis that is orthogonal to the first axis.
