Abstract

A magnetic field sensor may include a plurality of MTJ elements. Each MTJ element of has a state indicated by a magnetic moment direction of a sensing layer relative to a pinned, reference layer in an absence of an external magnetic field. The plurality of MTJ elements are arranged into two identical sets of at least two MTJ elements, where each MTJ element in each respective set has a different state. The states of the MTJ elements are arranged in a manner to measure the external magnetic field regardless of the direction of the external magnetic field. The MTJ elements include identical layers, and are electrically serially connected.
