A Signal Reconstruction Technique For Power Delivery Analysis

This document describes a signal processing technique to reconstruct the high-frequency current of a DDR4 DIMM at BGA level, by using the current measured at a remote shunt resistor.Simulation results using the reconstructed current show very good correlation with experimental data, proving that the...

Summary:This document describes a signal processing technique to reconstruct the high-frequency current of a DDR4 DIMM at BGA level, by using the current measured at a remote shunt resistor.Simulation results using the reconstructed current show very good correlation with experimental data, proving that the proposed approach is an accurate, reliable low-cost low-complexity characterization technique.
