Abstract
The innovative concept described herein relates to a sensor chip having at least two magnetic field sensors that are arranged adjacently to one another on the sensor chip and measure perpendicularly to the chip plane, wherein at least one of the magnetic field sensors has a planar coil arranged on it that is configured to generate a magnetic field directed perpendicularly to the chip plane. A controller is able to operate the magnetic field sensors in a calibration mode, in which the planar coil generates the magnetic field. For the purpose of calibrating the magnetic field sensors, a differential measurement may be taken that involves the response signal from one magnetic field sensor being subtracted from the response signal from the other magnetic field sensor.
