Current mode signaling (CMS) is found to be advantageous than voltage mode signaling (VMS) in VLSI interconnects. So, we propose the use of triangular carbon nanotube bundles as VLSI interconnects for CMS in VLSI circuits. T-CNT bundles have inherent advantages of lesser propagation delay and crosstalk delay than traditionally proposed square CNT bundle interconnects. We analyze the propagation delays of both the types of bundles in voltage and current mode signalling schemes and compare the improvement of propagation delay in both the cases. We find that T-CNT bundles perform better than square bundles in both the signalling schemes. © 2019 IEEE.
