ANALYSIS AND MODELING OF FREQUENCY-DEPENDENT RESISTANCE AND INDUCTANCE OF SINGLE CMOS INTERCONNECTS

Hasan Ymeri, B. Nauwelaers, Karen Maex

Abstract


A simple, efficient CAD-oriented analytic modeling approach to calculate frequency-dependent distributed inductance and associated distributed series resistance per-unit-length of single on-chip interconnects on a lossy silicon substrate is presented. The closed-form formulas for the frequency-dependent series impedance parameters are obtained using vector magnetic potential equation and a complex image technique. The proposed frequency-dependent inductance L(w) and resistance R(w) per-unit-length formulas are shown to be in good agreement with the electromagnetic solutions.
