1.5. Minimization Parasitic Inductances

The goal of a Power Distribution System (PDS) is to provide and maintain a target constant voltage at the power and ground pads of each device. To effectively accomplish this, the PDS relies on the Voltage Regulator Module (VRM), the bulk and decoupling capacitors (Decaps) and the power and ground plane sandwich (plane capacitance). How effectively each of these components perform their job in helping to maintain a constant voltage under varying transient loads depends highly on their associated parasitic inductances.
