Abstract

A system includes a multiturn counter that can store a magnetic state associated with a number of accumulated turns of a magnetic field. The multiturn counter includes a plurality of magnetoresistive elements electrically coupled in series with each other and a reference element. The plurality of magnetoresistive elements are formed in a magnetic strip. The reference element is separate from the magnetic strip. A strip width of the magnetic strip and a strip width of the reference element are similar. The plurality of magnetoresistive elements and the reference element can be coupled to a matrix of electrical connections.
