  • Circuit arrangement, lighting apparatus and method of crosstalk-compensated current sensing
    Patent number: 8952615
    Abstract: A circuit arrangement comprises a plurality of current channels located in different die areas of a shared circuit die, at least one of the plurality of current channels comprising a power device; at least one sense circuit connected to one or more of the different die areas and arranged to provide a sense current from sensing a current through a primary of the plurality of current channels comprising one of the different die areas. The at least one sense circuit comprises a compensation module arranged to provide a compensation current adapted to at least partly compensate a deviation of the sense current caused by crosstalk between the primary and one or more secondary of the plurality of current channels depending on one or more secondary currents flowing through the one or more secondary current channels; wherein the compensation module is arranged to provide the compensation current at least partly as a weighted sum of the one or more secondary currents.
