The design and performance of power distribution networks (PDNs) in modern printed circuit board (PCB) assemblies and application-specific integrated circuits (ASICs) are paramount for ensuring a stable and clean voltage to the load.1 To achieve this, accurate modeling of all elements of the PDN is essential.2 One often overlooked element is an accurate representation of the capacitors that filter voltage ripple at the load and provide a matched impedance from the source to the load.
