Abstract:
An integrated AMR angular sensor includes a first sensor resistor and a second sensor resistor. The first sensor resistor and the second sensor resistor each has a plurality of magnetoresistive segments containing magnetoresistive material that are electrically coupled in series. The magnetoresistive segments of each sensor resistor are parallel/anti-parallel to each other. The magnetoresistive segments of the second sensor resistor are perpendicular to the magnetoresistive segments of the first sensor resistor. The first magnetoresistive segments are divided into a first group and a second group, which are disposed in a balanced distribution relative to a sensor central point of the integrated AMR angular sensor. Similarly, the second magnetoresistive segments are divided into a first group and a second group, which are disposed in a balanced distribution relative to the sensor central point.
