Dynamic crosstalk effect in CNT bus architecture

This research paper observes dynamic crosstalk delay for different single and bundled carbon nanotube (CNT) structures. These CNT structures are implemented by using three coupled line bus architecture. HSPICE simulations are performed for different single and bundled single-walled and double-walled CNT (SWCNT and DWCNT) structures. A bundled DWCNT shows approximately 90.8% and 60.4% improvement in crosstalk induced time delay as compared to single and bundled SWCNT structures at 1000μm and 100μm interconnect lengths, respectively. This improvement is more progressive for bundled DWCNT with increasing interconnect lengths.
