bypass capacitor1 Buried CapacitanceTM: As electronic devices get faster, printed circuit boards need to be designed with high speed operation in mind. Consideration must be given to such design issues as power distribution, impedance, crosstalk and EMI, load distribution and board structure (See also “Appnotes: Entering The High-Speed Domain”). Buried CapacitanceTM can be utilized to improve power distribution and reduce EMI emissions in high frequency digital applications. Capacitance Basics A capacitor is formed when two conductive layers are separated by an insulative (dielectric) material. By applying different voltages to the conductive layers, energy is stored in the dielectric material which can be released rapidly to system components. The amount of energy (capacitance) is proportional to ……
