Abstract:
1. A circuit arrangement, comprising a plurality of current channels located in different die areas of a shared circuit die, at least one of said plurality of current channels comprising a power device; at least one sense circuit connected to one or more of said different die areas and arranged to provide a sense current from sensing a current through a primary of said plurality of current channels comprising one of said different die areas, said at least one sense circuit comprising a compensation module arranged to provide a compensation current adapted to at least partly compensate a deviation of said sense current caused by crosstalk between said primary and one or more secondary of said plurality of current channels depending on one or more secondary currents flowing through said one or more secondary current channels; wherein said compensation module is arranged to provide said compensation current at least partly as a weighted sum of said one or more secondary currents.
