1. An electrical circuit comprising:

  • at least one measuring resistor structure integrated in a semiconductor body;

    at least one further resistor structure integrated in the semiconductor body and thermally coupled to the measuring resistor structure; and

    a circuit arrangement electrically connected to the further resistor structure and configured to feed a current to the further resistor structure and evaluate a temperature-dependent voltage dropped across the further resistor structure, wherein the temperature-dependent voltage provides a signal used for temperature compensation of the measuring resistor structure.
