Fast crosstalk analysis of multi-walled carbon nanotube interconnects

In this paper, an efficient method based on the equivalent single conductor (ESC) model and delay extraction technique is presented to investigate the crosstalk effects of complex multi-walled carbon nanotube (MWCNT) interconnects. Each MWCNT interconnect is first characterized by the ESC model. A decoupling algorithm is then utilized to transform the coupled interconnects into a set of individual lines. After that, based on a modified Lie formula, a delay algebraic equation is derived to obtain the time domain response of each single interconnect. The validity and efficiency of the proposed method are demonstrated by the numerical example and compared with the original multiconductor circuit (MCC) model. Some discussions on the numerical results of crosstalk effects obtained by the two models are also given.
