A novel fractal PCB power plane for power integrity in high speed mixed signal system

Abstract

In this paper, a novel fractal PCB power plane based on leaf vein fractal structure is developed. The technique introduced here not only provide noise suppression over a wide range of frequencies, but also improve IR drop and Swiss Chess structure effect (high resistance metal areas because of distributed vias and solders and leading to the voltages or currents to the circuit elements lower than design demand).
