Extended adaptive voltage positioning (EAVP) [power delivery network design]

The aim of this paper is to present a new robust approach, named extended adaptive voltage positioning (EAVP), to the design and analysis of a low impedance power delivery network. EAVP utilizes and extends on the theory of adaptive voltage positioning (AVP) that is commonly used in voltage regulator module (VRM) design and operation. Using EAVP, the authors demonstrate how uncertainties in design guardband noise budget can be removed, resulting in significant performance bin-split improvement and cost reduction. Design optimization of decoupling capacitors is illustrated using EAVP by using both time and frequency domain analysis.
