Resonant free power network design using extended adaptive voltage positioning (EAVP) methodology

Extended adaptive voltage positioning (EAVP) is a new robust methodology for the design and analysis of a low impedance resonant free power delivery network, which utilizes and extends the theory of adaptive voltage positioning (AVP) that is commonly used in voltage regulator module (VRM) design and operation. Using EAVP, uncertainties in design guardband noise budget can be removed, resulting in significant performance bin-split improvement and cost reduction. Design optimization of decoupling capacitors with EAVP will be illustrated by using both time and frequency domain analysis
