Abstract
An anisotropic magnetoresistive (AMR) sensor without a set and reset device may include a substrate, an exchange bias layer, an AMR layer and a collection of barber-pole electrodes. The exchange bias layer may be deposited on the substrate and the AMR layer may be deposited on the exchange bias layer. The AMR layer may include multiple groups of AMR strips, and each group may include several AMR strips. The barber-pole electrodes may be arranged on each AMR strip. The AMR sensor achieves coupling by using the exchange bias layer, without requiring a reset/set coil. Because a coil is not used, the power consumption of the chip is reduced greatly, and the manufacturing process is simpler, providing improved yield and lower cost.
