The applications have, in turn, motivated a progression from traditional helical to recent miniaturized printed circuit board implementation, in order to improve the overall power density.

Power-bus resonance of printed circuit boards causes electromagnetic interference and detraction of power integrity. To suppress the power-bus resonance, we propose the application of lossy resonators ...
