Design of Power Based on Plant Vein for Printed Circuit Board
Chu Qing-xin · Journal of Microwaves · 2010
Increased chip functionality results in the need for a huge power distribution network.Lower supply voltage makes resistive voltage andSwiss Cheeseeffect very critical.In mixed-signal systems,effective noise isolation between analog and digital circuits is required for correct action.In this paper,a novel power plane has been proposed.The novel structure is designed based on leaf vein.The theory basis of the design is fractal theory and Murray's law.The designed power network can produce uniform current distribution and wide electromagnetic band gap.Our physical structures have greatly improved noise isolation andswiss cheeseeffect.
