    <title language="eng">CMOS Integrated Field Coils for Self-Calibration of 3D Hall-Sensors</title>
    <abstract language="eng">An integrated arrangement of field coils for on-chip self-calibration is presented. Routine tests for 3D Hall sensors are very complex and need special test hardware to generate a well-defined three-dimensional magnetic field. In combination with a high voltage current source, the integrated arrangement allows the generation of local magnetic fields up to 2 mT. In spite of process variations, the error of each coil's magnetic flux density is less than 1%. Magnetic tests can be done on-chip without need for additional external test equipment. Additionally, a low power mode allows for validity checks and online calibrations during measurements with a small magnetic flux density of 0:2 mT.</abstract>
