摘要

We show system modeling and measurement results of a platform with array capacitor solution (ACS) within the frequency domain. A Pentium® 4 microprocessor package was redesigned for a single array capacitor, in place of all multi-terminal capacitors. Its system power delivery impedance profile was found to have a more desirable high frequency response than the earlier system designed with discrete multi-terminal capacitors. These measured results were also found to agree well with the behavior predicted by simulation models. Additionally we explore the impact and optimization of array capacitor parameters on the overall system frequency response.
