Abstract:
Carbon based interconnects have shown immense
potential as a candidate to replace traditional copper
interconnects for on-chip applications. In that, 2D Graphene
Nanoribbon (GNR) interconnects offer superior electrical
properties owing to larger mean free paths of electrons and
better current carrying capabilities. Single-layer GNR
interconnects can be considered as the simplest form of
planar carbon-based interconnects for on-chip applications.
In this paper, we present closed-form models for computing
transfer function of single-layer GNR interconnects.
Further, we present the transient analysis of these
interconnects, in that we report analytical solutions for 50%
delay time, 90% rise time and energy dissipation. The
proposed models exhibit excellent accuracy when compared
to simulated data while providing physical insights into the
effect of quantum capacitance on 50% delay and energy
estimation. The proposed models are highly accurate, in that
they closely match with data generated from simulations as
well as that in the previously published literature.
