Abstract
The power distribution network spans many layers of interconnect with disparate electrical properties. The impedance characteristics of multi-layer power distribution grids and the relevant design implications are the subject of this chapter.Decoupling capacitors are an effective technique to reduce the effect of the inductance on power distribution networks operating at high frequencies. The efficacy of decoupling capacitors depends on the impedance of the conductors connecting the capacitors to the power load and source. The optimal allocation of the on-chip decoupling capacitance depends on the impedance characteristics of the interconnect. Robust and area efficient design of multi-layer power distribution grids therefore requires a thorough understanding of the impedance properties of the power distributing interconnect structures.
