Abstract
A magnetoresistance element structure disposed parallel to an x-y plane defined by an x-axis and a y-axis orthogonal to the x-axis can include a first magnetoresistance element having a plurality of first shapes coupled in series to result in the first magnetoresistance element having a first serpentine shape parallel to the x-y plane; and a second magnetoresistance element having a plurality of second shapes coupled in series to result in the second magnetoresistance element having a second serpentine shape parallel to the x-y plane, wherein the plurality of first shapes and the plurality of second shapes are disposed in an interdigitated pattern. A magnetic field sensor can use the above magnetoresistance element structure. Nested magnetoresistance elements and magnetic field sensors are also described.
