Abstract
Reducing differential mode (dm) noise of switching converters in an effective way is an open issue. Here, a thorough investigation of the filtering technique with integrated magnetics combined with a sensitivity analysis for mismatches in the coupling factor is done together with an analysis of the optimized distribution of capacitance between the two capacitors involved. The whole analysis is done in the frequency domain. Therefore, a proper model is given.
