bypass capacitor1Buried CapacitanceTM:As electronic devices get faster, printed circuit boards need to bedesigned with high speed operation in mind. Consideration must be given tosuch design issues as power distribution, impedance, crosstalk and EMI,load distribution and board structure (See also “Appnotes: Entering TheHigh-Speed Domain”). Buried CapacitanceTM can be utilized to improve powerdistribution and reduce EMI emissions in high frequency digitalapplications.Capacitance BasicsA capacitor is formed when two conductive layers are separated by aninsulative (dielectric) material. By applying different voltages to theconductive layers, energy is stored in the dielectric material which can bereleased rapidly to system components. The amount of energy (capacitance)is proportional to ……
