Investigation and comparison of analog figures-of-merit for TFET and FinFET considering work-function variation
TFET exhibits superior variation immunity regarding the gm/IDS, Rout and intrinsic gain as compared with the FinFET counterparts. TFET exhibits comparable variability in gm and fT as compared with the FinFET counterparts. The correlations between pertinent parameters (e.g., gm and Rout) impacts on the variation immunity of important analog FOMs are analyzed.
