Estimation of parasitic elements of multilayer ceramic capacitors

The analysis of decoupling networks for high-speed integrated circuits (IC) used today in most applications, as well as the analysis of the impedance of capacitor networks for most power supplies can prove to be a real challenge for electrical designers today. This paper presents a method of estimating the impedance and equivalent series resistance variation with frequency of multilayer ceramic capacitors and provides a quick solution to an otherwise time consuming approach to analyze the equivalent impedance of various capacitor networks in different applications.
