Abstract
Apparatuses, methods and systems of a magnetic sensor self-characterizing its magnetic properties are disclosed. One embodiment of the magnetic sensor apparatus includes a magnetic sensor and a current source for applying a current to the magnetic sensor. The magnetic sensor apparatus further includes control circuitry configured to control the current source, and characterize a magnetic property of the magnetic sensor based on the applied current. One method of a magnetic sensor self-characterizing its magnetic properties includes applying, by the magnetic sensor, an electrical signal, and characterizing a magnetic property of the magnetic sensor based on the applied electrical signal.
