current was 40 A. The waveforms show the effect of capacitor depopulation on the impedance profile above 1 MHz as pairs of high frequency MLCC capacitors are removed (banks 1-9) per the bank designations depicted in Figure A-7.

Simulation comparisons are made in Figure A-8for the two extreme cases of the decoupling conditions of Figure A-7, with all MLCC plus two Al-Poly bulk capacitors in place and all cavity MLCCs plus two Al-Poly bulk capacitors removed. Simulation depicts a 6-layer distributed motherboard model. The VR model has a Type III feedback compensated switching VR (swvr) and an average model (avgvr). It can be observed from Figure A-8that the switching model measurements agrees better beyond the VR bandwidth (40 kHz) than the average model, while the average VR model performance agrees with the overall trend. Slightly lower average model impedances are also observed and other disagreements are attributed to imperfect assumptions about the parasitics of the devices and specific adaptive voltage implementation in the VR models.
