Analysis of signal transmission along graphene-based interconnect structures

The signal transmission along interconnect based on graphene nanoribbon (GNR) is studied in this paper. Equivalent circuit models are implemented to characterize graphene-based interconnect and analyze its signal integrity. In equivalent circuits models, the inter-layer mutual impedance (capacitance and inductance) between adjacent layers has been taken into consideration. Meanwhile, we proposed both equivalent circuit and full-wave method to analyze the effect of bended part of graphene-based interconnect. With the help of equivalent circuits, input/output voltage of different interconnect structures is explored. Moreover, eye diagram is utilized for further study of several kinds of graphene interconnects' signal integrity.
