Crosstalk and delay analysis

Abstract

This chapter analyzes and compares the power, delay, and crosstalk performance of different CNT based interconnects in form of single and bundled SWNT, DWNT, and MWNT. The equivalent electrical models of CNT interconnects represent the interconnect line of a driver-interconnect-load (DIL) setup. The motivation behind using CMOS driver to drive the interconnect line is briefly discussed. The DIL setup is primarily used to analyze the propagation delay, whereas a capacitively coupled three-line bus architecture is used to analyze the crosstalk induced delay. The propagation delay under the influence of crosstalk is analyzed for different interconnect lengths, transition time, and spacing between coupled lines (aggressor and victim).
