Analysis of Crosstalk Deviation for Bundled MWCNT with Process Induced Height and Width Variations - VLSI Design and Test - page 221

having MWCNTs with 5-shells, the difference between minimum and maximum
number of conducting channels is lesser in comparison to the bundle having
MWCNTs with 5- and 15-shells as observed from Table 3. The minimum difference
in conducting channels reveals to the minimum difference in interconnect parasitics
for the bundle having MWCNTs with 10-shells. Therefore, the bundle having
MWCNTs with 10-shells exhibits higher crosstalk deviation in comparison to the
bundle having MWCNTs with 5- and 15-shells.

5 Conclusion

This research paper presented an analytical model of bundled MWCNT that uses the
total number of conducting channels to model the interconnect parasitics. To analyze
the crosstalk delay, the equivalent RLC line of bundled MWCNT has been used to
represent the capacitively coupled interconnect lines. Monte Carlo simulations are
performed to analyze the average crosstalk deviation for process induced bundle
heights and widths variations. Using Gaussian distributed bundle widths and heights,
it has been observed that the average crosstalk deviation reduces for the bundle
having MWCNTs with higher number of shells.
