Publication number: 20180172779Abstract: A central idea of techniques herein is that by means of modulation or variation of the supply signal of a Hall sensor, the useful signal portion in the resulting sensor output signal can be separated from the offset portion during operation of the Hall sensor, with no previous calibration or previous serial tests. That course of the sensor output signal resulting from the modulation or variation of the supply signal can then be evaluated or decomposed relative to the components which can be attributed to the offset portion and the useful signal portion. Thus, the offset portion in the sensor output signal can be determined with no (or a negligibly small) external magnetic field applied or with an external magnetic field applied, in case the external magnetic field is constant within a tolerance range while determining the offset portion.Type: ApplicationFiled: December 15, 2017Publication date: June 21, 2018Inventors: Markus STAHL-OFFERGELD, Markus SAND, Hans-Peter HOHE
