Abstract: A sensor includes first and second magnetoresistive sensor elements configured to produce respective first and second output signals in response to an external magnetic field. The first and second magnetoresistive sensor elements form a gradient unit, each of the magnetoresistive sensor elements includes a sense layer having a vortex magnetization pattern. A processing circuit is coupled to the sensor elements and is configured to produce a differential output signal as a difference between the first and second output signals of the first and second magnetoresistive sensor elements of the gradient unit. The system includes an encoder that produces the external magnetic field and the sensor having one or more gradient units, in which the gradient units may be arranged in a second-order gradient sensing configuration.
