Magnetic sensor device and method of determining resistance values |
摘要 |
A magnetoresistance sensor has a first magnetic layer that changes polarity in response to an external magnetic field and a second magnetic layer having a fixed magnetic polarity oriented in a reference direction. A varying voltage is applied to establish a varying magnetic bias field in the reference direction. An evaluation circuit calculates the difference between maximum and minimum resistance values established in response to the external magnetic field.
