1. An anisotropic-magnetoresistive (AMR) sensor with improved linearity, comprising:
a continuous strip of magnetoresistive material, the strip comprising a first section having a first constant width and a second section having a second constant width greater than the first constant width, wherein the strip of magnetoresistive material is configured such that a supply voltage is applied to an input end of the second section, and wherein an output end of the second section is positioned between the input end of the second section and the first section;
a first plurality of conductive strips arranged on the first section and oriented at a first angle relative to the strip of magnetoresistive material, and extending over the first constant width; and
a second plurality of conductive strips arranged on the second section and oriented at a second angle relative to the strip of magnetoresistive material, and extending over the second constant width, wherein the first angle is opposite the second angle with respect to a line parallel to the first and second constant widths and perpendicular to a length of the strip of magnetoresistive material.
