I-V Method Based PDN Impedance Measurement Technique and Associated Probe Design

Abstract

In this paper I-V method-based impedance measurement of power distribution network (PDN) in printed circuit board (PCB) technique is proposed and compared to the traditional VNA method [1]. A I-V method-based probe is designed and verified by comparing the performance with VNA method. To de-embed the parasitic problems, a special I-V probe calibration method is created according to the characteristics of the probe.
