Crosstalk Induced Performance Analysis of Single Wall Carbon Nanotube Interconnects Using Stable Finite-Difference Time-Domain Model

摘要

In this work, a novel stable finite-difference time-domain (FDTD) method is proposed to evaluate the coupled single wall carbon nanotube (SWCNT) interconnect system. The proposed FDTD method accurately analyses the crosstalk effect by integrating the variation of parameter effects such as: interconnect parasitic elements, driver aspect ratios, supply voltages, ambient temperature and load capacitances. From the transient response comparison, we observed that the proposed FDTD method is superior to the conventional FDTD in terms of both runtime and stability. The proposed model consumes lesser time compared to the conventional FDTD and the stability is not constrained by the Courant-Friedrichs-Lewy (CFL) stability condition. Further, the relative stability analysis of proposed FDTD is analyzed using Bode plot and Root locus.
