Single layer sheets of graphene show special electrical properties that can enable the next generation of smart ICs. Recent works have proven the availability of an electrostatically controlled pn-junction upon which it is possible to design multifunction reconfigurable logic devices that naturally behave as multiplexers. In this work we introduce a stable large-signal Verilog-A model that mimics the behavior of the aforementioned devices. The proposed model, validated through the SPICE characterization of a MUX-based standard cell library we designed as benchmark, represents a first step towards the integration of Electronic Design Automation tools that can support the design of all-graphene ICs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
