Crosstalk Noise Modeling for Coupled SWCNT Bundle Interconnects using MRTD Technique
Dr. Bhaskar Gugulothu & Dr. B. Rajendra NaikThis paper analyzes the crosstalk effects of resistive driven single-walled carbon nanotube (SWCNT) bundle interconnects. The wavelet-based numerical model Multiresolution Time Domain (MRTD) approach is used for interconnects analysis. The performance of the proposed model MRTD against the traditional Finite Difference Time Domain (FDTD) model and the SPICE tool is used to evaluate the global interconnects at 32nm technology node. Mathematical equations are done using MATLAB. For various test cases, the effect of line resistances on crosstalk effects were evaluated for delay measurement, while in-phase, out-phase and functional crosstalk, the average errors is observed to be less than 2.9%, 1.86% and 1.78% respectively, and also the estimated noise peak voltage, is less than 1 percent on average. In that observation, proposed MRTD model dominates the traditional FDTD as accurately as the results of the SPICE simulation. This approach can be used to resolve the problems of electromagnetic interference and electromagnetic compatibility of on-chip interconnects.
