Crosstalk Stability Analysis in Multilayer Graphene Nanoribbon Interconnects

Abstract

In this paper a time-domain response and Nyquist stability criterion to acquire dependence of degree of crosstalk relative stability based on transmission lines modeling (TLM) is investigated for coupled multilayer graphene nanoribbon (MLGNR) interconnects. This is the first instance that such an analysis has been presented for coupled MLGNR consisting of both capacitive and mutual-inductive couplings. The near-end and far-end outputs of coupled MLGNR individually are compared in two cases, with considering both couplings and without them (single MLGNR). It is observed that the near-end output of the system together with both couplings is more stable and at its far-end output, an induced voltage is created. By increasing capacitive coupling or decreasing inductive coupling, the near-end output becomes more stable. Also, the results of changes of length and width of each ribbon show that by increasing the length and decreasing the width, the coupled MLGNR interconnects become more stable.
