A decoupling technique on switch factor based analysis of RLC interconnects

Abstract

In recent years, as the density of the components in the integrated circuit grows, the distance between the on-chip wires becomes smaller. The crosstalk is more important and will change the signal waveform or generate logic failures and then degrade the performance and the reality of the circuit. In this paper, we focus on the response of the transmission line and the value of the crosstalk noise. We propose a new method to obtain the equivalent circuit, and it is of a closed form which is suitable for the coupled circuit composed of multiple coupling capacitors and mutual inductors. In one general coupled circuit with two lines in which there are different resistances and capacitances between line and ground and different slopes of the source voltages, we refer to the parameters in other papers and use our approach to estimate the propagation delay. By comparing with the result obtained from simulating the circuit with HSPICE, we achieve an average error rate around 5%.
