Abstract
The first radio frequency (RF) noise measurements on lateral nanowire metal-oxide-semiconductor field-effect transistors (MOSFETs) and a noise model are presented. We have characterized the RF noise and scattering parameters of an indium gallium arsenide (InGaAs) device. A fitted model yields extrapolated ft = 316 GHz current gain cutoff and fmax = 166 GHz maximum oscillation frequency. This device technology is being developed for millimeter wave circuit implementations, targeting a 94 GHz carrier frequency. The modeled intrinsic Fmin < 1dB minimum noise figure obtained promises performance at the target band, given reduction of gate parasitics. In any wireless system, noise and bandwidth limits the performance. Understanding of RF noise in nanowire MOSFET devices is thereby key for realization of future radar and communications systems.
