Performance Evaluation of Pass-Transistor-Based Circuits using Monolayer and Bilayer 2-D Transition Metal Dichalcogenide (TMD) MOSFETs for 5.9nm Node

We comprehensively evaluate and benchmark the performance of pass-transistor logic (PTL) circuits using monolayer and bilayer transition metal dichalcogenide (TMD) devices based on ITRS 2028 node. Our study indicates that the higher V-T of bilayer TMD devices significantly degrades the performance of single pass-transistor based circuits compared with the monolayer counterparts despite the higher mobility of bilayer TMD devices. The effect can be mitigated by using full transmission gate or providing a complementary path.
