Accurate Numerical Model for Crosstalk Analysis of SWCNT Bundle Interconnects Using FDTD Method

This paper presents an accurate and efficient numerical model for the crosstalk analysis of coupled single wall carbon nanotube (SWCNT) bundle interconnects using finite-difference time-domain (FDTD) method. Using the proposed model the voltage and current can be accurately estimated at any particular point on the interconnect line and furthermore, the model can be extended to n coupled interconnect lines with a low computational cost. Crosstalk induced performance parameters are measured using the proposed model and validated by comparing it to the HSPICE simulations. It is observed that the average error in estimating the noise peak voltage on a victim line is less than 1%. The proposed model is extremely useful for accurate estimation of crosstalk induced performance parameters of SWCNT interconnects.
