Method and apparatus for the compensation of dynamic error signals of a chopped hall sensor

摘要

A method for compensation of dynamic error signals of a chopped Hall sensor that comprises at least one Hall sensor element comprising a plurality of terminal pairs for impressing an excitation current through the Hall sensor element and for taking a Hall voltage. The terminal pairs for impressing the excitation current and for taking the Hall voltage are switched in a first and/or second rotational sense. In order to compensate dynamic error signals caused by the switching, the Hall voltages taken at the terminal pairs when switching in the first rotational sense are supplied to a summation and/or averaging analysis unit together with the Hall voltages taken at the terminal pairs when switching in the second rotational sense.
