Additivity of Capacitive and Inductive Coupling in Submicronic Interconnects

Abstract : Constant evolution in integrated circuit technology has led to an increase in the switching speed of the digital chip. As a result, there is a growing interest in the inductance associated with signal lines. Inductive coupling effects on interconnects is an emerging concern in high performance digital integrated circuits. Based on an RLC transmission line model, associated to each propagation mode, a new crosstalk noise model is proposed to evaluate both the capacitive and the inductive coupling. The additivity of the coupling is shown and validated with several simulations.
