Inserting frequency compensation as needed for stable response. PDN designs may be classified as tightly or loosely coupled through the effective frequency range of the VRM bulk capacitors.
At capacitor switching while one or more capacitors are connected to the system, the switching capacitor will see a high inrush current. This is due to the current flow from the already connected capacitor(s) (which will act as a source) through the least impedance path set by the switched capacitor along with the current from the main source. This means that when the number of …
