Abstract
A method of estimating a Miller coefficient for an aggressor network and a victim network coupled by a coupling capacitor includes synthesizing a reduced order system from the aggressor network and the victim network, estimating an active area across the coupling capacitor for an aggressor induced noise signal based on the reduced order system, calculating an estimate of the Miller coefficient based on the active area of the aggressor induced noise signal, and outputting the calculated estimate of the Miller coefficient.
