Fig. 2 Measurement configuration of PDN
Because of practical reasons, we measured S parameters;
eventually we converted the results to Z parameters. Once the
measurements had been done, the impedance model was
extracted. It represents a first order resonance, obtaining the
global resistance value R at the frequency resonance. But before
setting up the impedance model, we should remove the effects
of the PCB board, conductive path between the power supply
pin and SMA connector, and SMA connector. De-embedding is
a mathematical method that removes the undesirable effects of
