Analysis of Crosstalk Deviation for Bundled MWCNT with Process Induced Height and Width Variations

Process variation is an important design concern in current nanoscale regime. This research paper analyzes the effect of process induced height and width variations for a multi-walled carbon nanotube (MWCNT) bundle interconnects. For different bundle heights and widths, the average deviation in crosstalk delay is analyzed for bundles having MWCNTs with different number of shells. A capacitively coupled interconnect line is used to analyze the crosstalk delay by using the Monte Carlo simulations with 100 different samples. Using Gaussian distributed widths and heights, a bundle having MWCNTs with higher number of shells exhibits least deviation in crosstalk.
