Abstract: The present disclosure relates to a PCB and a method in the PCB for reducing common-mode current. The PCB comprises two differential lines and each of the differential lines is on one or more planes of the PCB. The two differential lines carry a differential mode current and the common mode current. The differential mode current and the common mode current may be at least one of a forward current and a backward current. Further, a predefined configuration is formed using each of the two differential lines to generate impedance at the predefined configuration. Here, the predefined configuration is placed close to each other to generate a dielectric capacitance. The flow of the forward current and the backward current in adjacent tracks of each of the two differential lines in the predefined configuration are in opposite direction.
