Based on the transmission line modeling for multilayer graphene nanoribbon (MGNR)
interconnects, system stability was studied on intrinsic parameters. In addition to width,
length and height variation, dielectric constant, permeability and Fermi velocity path
change in multilayer graphene nanoribbon (MGNR) interconnects are analyzed. In this
paper, the obtained results show with increasing dielectric constant and decreasing
permeability, Fermi velocity system becomes more stable. Nyquist diagram and step
response method results confirm these and are matched with physical parameter variation
like resistance, capacitance and inductance in the following sensitivity analysis results where
it shows with increasing width and length, sensitivity will decrease and increase respectively.
Impulse response diagram results show with increasing 50% width, sensitivity will be zero
but with increasing 50% length, amplitude will decrease and the time of setting will increase.
On the other hand, from the step response of the transfer function, both width and length
increase cause more stability for a system but the width parameter will be a better choice
for manipulating the dimension of MGNR to reach a stable system.
