Using a microstrip line layout, a low minimum noise figure (NF min) of 0.51 dB, at 10 GHz, was directly measured for 90 nm node NMOSFETs (65 nm physical gate length). The NFmin was located at the peak fT of 152 GHz, coinciding with the peak transconductance (g m). On the basis of these measurements, a self-consistent model of the DC I-V, S-parameters, and NFmin results was developed, including the changes after hot-carrier stress.
