Abstract: In the paper, we experimentally
characterized the four methods and assessed both current method and voltage
method based on its test schematics. The accuracy of the current method was
analyzed based on current probe performance and circuit parasitic parameter
performance (such as parasitic inductance), while the accuracy of voltage
method was studied based on coupling capacitance performance and insertion
component performance. The resonance effect was further investigated for
differential mode noise source impedance extraction. We finally proposed a
novel design and our theoretical analysis; simulation and experiment results
showed that the conductive EMI noise can be reduced effectively by our
innovative approach.
