Abstract
Compensation coil functionality and flip coil functionality are combined into a single combination coil that is placed under an angle α with respect to the length direction of a magneto-resistive sensor element. The angle α substantially deviates from 0° and 90°. This configuration enables to reduce the width of the current line of the planar combination coil, to reduce the effective threshold for sensor element switching, and to include features to simplify a 2D sensor design.
