Analytical Expressions for Capacitive and Inductive Coupling

In this paper, a new crosstalk RLC noise expression is proposed, based on an RLC transmission line model associated to each propagation mode, which is capable of predicting the noise amplitude and the noise pulsewidth of an RLC interconnect. Several simulations reveal that the proposed expression predicts the peak crosstalk noise and the pulsewidth with a good level of accuracy. This simplified analytical expression of crosstalk noise is sufficiently accurate to be effectively incorporated in noise calculators state-of-the-art

High-Frequency Effects of Orthogonal Interconnect Layers on Inductance in High-Speed VLSI Circuits

This communication deals with frequency behavior of orthogonal interconnect layers on inductance in high-speed VLSI circuits. The RLC parameters of the distributed model are determined by electromagnetic simulations. We evidence the error made on inductance in the range 1-50 GHz for three traditional interconnect configurations. A time-domain analysis highlights the impact of the inductance error on digital signals propagation. This analysis uses a numerical tool to take into account the frequency dependence of RLC parameters
