Abstract
A common mode inductor () for suppression of common mode noise and transmission of a differential signal is disclosed. The inductor comprises a core () with a first and second winding (), wherein the first winding and the second winding forms a pair of conductors arranged to convey a differential communication signal. Further, a third and fourth winding () is arranged to extend along at least a portion of the first and second winding, respectively. The third winding and the fourth winding may be locally inductively coupled to the first winding and the second winding, respectively. Moreover, the third winding and the fourth winding are connected in series with each other so that differential signal on the first and second windings transformed to the third and fourth winding maybe added to each other. The third and fourth winding may hence provide a sensor signal induced by the differential communication signal in the first winding and the second winding. A system () comprising the common mode inductor and a method for measuring a differential signal in said inductor is also disclosed.
