Modeling of crosstalk effects in coupled MLGNR interconnects based on FDTD method

This paper presents an accurate and efficient model for the crosstalk analysis of coupled multilayer graphene nanoribbon (MLGNR) interconnects using finite-difference time-domain (FDTD) technique. The proposed model can be used for accurately estimating the voltage and current at any particular point on the interconnect line. The model is further extended to coupled-n 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 and propagation delay is less than 2%.
