EXTERNAL MAGNETIC FIELD ANGLE DETERMINATION
Abstract:
Magnetoresistive sensors are commonly used for angular detection in many automotive applications. According to an exemplary embodiment of the present invention, a sensor is provided in which a first half-bridge has magnetoresistive resistors with barber-pole stripes and in which a second half-bridge has magnetoresistive resistors without barber-pole stripes. One of the resistors without barber-pole stripes is rotated with respect to the other three resistors by 90°. This may provide for an improved angle determination with reduced angular errors due to offset.
