"Measuring Milliohm PDN Components with a 50 Ohm VNA"

Measurement is a critical part of design flow as the ultimate anchor to reality. It enables us to verify simulation results and to characterize components before we commit to using them in our products. But in the power delivery network, impedances of components like capacitors and vias and VRMs and even planes can be very low, easily in the milliohm range. How can we possibly measure such low impedances with a network analyzer having 50 Ohm port impedances? This brief lecture will show a very simple technique to measure PDN components with a 2-port network analyzers.
