本論文主要在研究伺服器電路板中之電壓調節模組(Voltage regulator module, VRM)，於電晶體切換時所造成的電源切換雜訊(Switching Power Noise)問題。此高頻的電源切換雜訊可能會透過耦合的方式影響到鄰近的訊號線，進一步干擾系統的電源遞送網路(Power Delivery Network, PDN)，影響整體電路的電源完整性(Power Integrity)。本文著重在電源切換雜訊之參數萃取及建構電壓調節模組的等效電路模型，透過諧振頻率原理進行參數萃取，並使用系統性的方式建構等效電路模型，來改善本實驗室先前所提出之簡化電路架構，並模擬暫態電壓之波形。本論文所提出之參數萃取方式可有效萃取電壓調節模組之電感及電容參數，並且可在簡化電路模擬中得到相當精準的諧振頻率。

This thesis is study about the voltage regulator module (VRM) in the server board and the problem of switching power noise caused by the switching of transistors in VRM. This high-frequency switching power noise may affect adjacent signal lines through coupling, interfere with the power delivery network (PDN) of the system, and affect the power integrity of the overall circuit. This thesis focuses on the LC parameter extraction of the switching power noise and the construction of the equivalent circuit model of VRM. The parameter extraction method is according to the principle of resonance frequency and the equivalent circuit model, which improves the previous model proposed by this lab, is constructed to simulate the transient voltage waveforms. The parameter extraction method proposed in this thesis can effectively extract the inductance and capacitance parameters of VRM and can obtain a fairly accurate resonance frequency by the equivalent circuit model.
