Abstract
A shunt resistor includes: two measuring terminals for applying a measuring current flowing through the shunt resistor along a main flow direction; slot structures dividing the shunt resistor along the main flow direction to include two side flow areas of respective first widths and a main flow area of a second width; and two calibration terminals connected to the side flow areas. A circuit connected to the measuring terminals is designed to detect, and generate a signal based on, a measuring current flowing through the shunt resistor. A calibration device connected to the calibration terminals is designed to apply a reference voltage or current to the calibration terminals, and ascertain a calibration voltage based on a falling voltage across those terminals. A correction circuit connected to the calibration device and the detection circuit is designed to correct the signal generated by the detection circuit based on the detected calibration voltage.
