Abstract
System-level power distribution network (PDN) impedance optimization utilizing the zeros of the decoupling capacitors (decaps) is discussed in this paper. An example of a practical PDN application is proposed to validate the poles and zeros algorithm (P&Z) presented. The system-level PDN is with the printed circuit board (PCB), package (PKG), and chip, as well as the low-frequency decaps on the PCB and the on-PKG decoupling capacitors. The PDN optimization results are compared with those from the genetic algorithm (GA) to show the reasonableness and validity of the P&Z algorithm.File in questo prodotto:
