Abstract
A magnetic sensor module includes an axially polarized back bias magnet having a body that radially extends from an inner sidewall to an outer sidewall and a bore that defines the inner sidewall. The magnet generates a radially symmetric bias magnetic in-plane field about a center axis in a sensor plane. The magnetic field has a magnetic flux density of substantially zero along the extension of the center axis and at a circumference of a zero-field circle located in the sensor plane, where the circumference of the zero-field circle vertically overlaps with the magnet body in a plan view. The magnetic sensor module includes a magnetic sensor including at least three sensor elements arranged in the sensor plane at locations where the radially symmetric bias magnetic in-plane field has a magnetic flux density of substantially zero, including at least two sensor elements being arranged on the circumference of the zero-field circle.
