Inductance Model of Decoupling Capacitors Including the Local Environment
The key purpose of power distribution networks is to maintain a low impedance power source for integrated circuit(s) for the stable supply voltage. In this paper, using the equivalent series capacitor inductance leads to inaccurate estimates of power bus impedance. A simple modeling approach is presented to estimate the inductance associated with the decoupling capacitors which accounts for the capacitor geometry, for connections to the capacitor, and for the capacitor height above the return plane.
