Abstract :
The crosstalk effects in single- and double-walled carbon nanotube bundle bus architectures are investigated and compared in this paper. New equivalent circuit models are proposed for both the single- and double-walled carbon nanotube bundles. It is found that (a) compared to single-walled carbon nanotube (SWCNT) bundle, a double-walled carbon nanotube (DWCNT) bundle bus can lead to a reduction of the crosstalk induced time delay by about 50%, and a slight reduction of delay uncertainty when the tubes are long; and (b) the peak voltage of the crosstalk induced glitch in the SWCNT bundle is lower than that in the DWCNT bundle, but the glitch duration time of the SWCNT bundle is longer than its DWCNT counterpart. These results confirm that the DWCNT bundle bus is more suitable for the next generation of bus technology and its overall performance will be better than that of SWCNT bundles.
