摘要
Several methods are presented for achieving a desired value of electrical impedance between parallel planar conductors of an electrical power distribution structure by electrically coupling multiple bypass capacitors between the planar conductors. The methods include bypass capacitor selection criteria based upon simulation results. An exemplary electrical power distribution structure produced by one of the methods includes a pair of parallel planar conductors separated by a dielectric layer, and n discrete electrical capacitors electrically coupled between the planar conductors, where n=2. The n capacitors have substantially the same capacitance C, mounted resistance Rm, and mounted inductance Lm. The electrical power distribution structure achieves an electrical impedance Z at a mounted resonant frequency fm-res of the capacitors. The mounted resistance Rm of each of the n capacitors is substantially equal to (n.Z). The mounted inductance Lm of each of the n capacitors is less than or equal to (0.2.n.mu0.h), where mu0 is the permeability of free space, and h is a distance between the planar conductors. The mounted resistance Rm of each capacitor is the sum of an equivalent series resistance (ESR) of the capacitor and the electrical resistances of all conductors coupling the capacitor between the planar conductors. The mounted inductance Lm of each capacitor is the electrical inductance resulting from the coupling of the capacitor between the planar conductors. The mounted resonant frequency fm-res results from capacitance C and mounted inductance Lm.
