Abstract
A magnetic sensor device comprises a substrate, first and second magnetic sensors, and one or more inductors are disposed over the substrate and are controlled by a magnetic sensor controller having a control circuit. The control circuit controls the first magnetic sensor to measure a first magnetic field and the second magnetic sensor to measure a second magnetic field under presence of a fifth magnetic field generated by the inductors. The control circuit controls the first magnetic sensor to measure a third magnetic field and the second magnetic sensor to measure a fourth magnetic field under presence of a sixth magnetic field generated by the inductors, the fifth magnetic field and the sixth magnetic field being different. The control circuit calculates a relative sensitivity matching value converting magnetic field values measured by the second magnetic sensor to a comparable magnetic field value measured by the first magnetic sensor.
