Abstract
Multilayer Graphene Nano-ribbons (MLGNRs) have been considered as a potential solution to replace conventional Cu for next-generation on-chip interconnects. In this paper, analytical models of transfer gain and crosstalk are derived for coupled three-line MLGNR interconnects using ABCD modeling approach. For this purpose, an equivalent single conductor model of GNRs has been considered. Our proposed model takes into account the impact of mutual inductive and capacitive coupling among the adjacent interconnects. Using the proposed model, the bandwidth of MLGNRs has been determined. It is found that GNR interconnects exhibit higher bandwidth, lesser delay and power as compared to Copper counterparts. The impact of input switching, transition time and interconnect length on crosstalk delay has also been investigated. The proposed analytical results agree well with SPICE simulations.
