Temperature dependent IR-drop and delay analysis in side-contact multilayer graphene nanoribbon based power interconnects

In this paper, we have analyzed the temperature dependent average IR-Drop and delay of side-contact multi-layer graphene nanoribbon (MLGNR) based power interconnects. The above analysis has been performed using our previously developed model using 16nm ITRS technology node. For a temperature ranges from 150K to 450K, the variation of resistance of MLGNR interconnect is ~2-5× lesser than that of traditional copper based power interconnects. Our analysis shows that MLGNR based power interconnects can show ~2-3× reduction in average IR-drop and ~1.5-2.72× reduction in delay as compared with copper based interconnects for local, intermediate and global interconnects.
