Small-Signal Performance and Modeling of sub-50nm nMOSFETs with f above 460-GHz

{{output}}
We have fabricated and tested the performance of sub-50nm gate nMOSFETs to assess their suitability for mixed signal applications in the super high frequency (SHF) band, i.e. 3-30GHz. For a 30nm×40 μm×2 device, we found f(T) =465GHz at V(ds)=2V, V(g)=0.67V,... ...
