"Accurate characterization of the dielectric properties of the laminate materials used in printed circuit board fabrication is critical for maximizing the performance of modern high speed circuitry. While many techniques exist for characterizing dielectric materials, most existing techniques are either limited in accuracy or highly impractical for use with planar, copper-clad laminate sheets. A common method involves forming a cavity from the printed circuit board material and calculating the permittivity and dissipation factor from the measured resonant frequencies and quality factor of the cavity. This resonance technique makes the assumption of an ideal cavity, which leads to errors in both …

"Power Distribution Network (PDN) for Printed Circuit Board (PCB) design requires proper power integrity analysis. In order to deliver a low-ripple DC voltage from a Voltage Regulator Module (VRM) to an Integrated Circuit (IC), a certain target input impedance should be achieved. Developing simple physics-based equivalent circuit models are essential for understanding how a system works and making crucial design decisions. In this work, the input impedance of a decoupling capacitor due to traces, pads and via discontinuities are investigated using the Physics-based Model Size Reduction (PMSR) method. Various decoupling capacitor connection methods are compared and design guidelines are provided …
