Abstract
A magnetic field sensor includes a plurality of magnetoresistance elements, each having at least one characteristic selected to provide a respective, different response to an applied magnetic field, wherein each of the plurality of magnetoresistance elements is coupled in parallel. Illustrative characteristics selected to provide the respective responses include dimensions and/or construction parameters such as materials, layer thickness and order, and spatial relationship of the magnetoresistance element to the applied magnetic field. A method includes providing each of a plurality of magnetoresistance elements with at least one characteristic selected to provide a respective, different response to an applied magnetic field, wherein each of the plurality of magnetoresistance elements is coupled in parallel.
