60 GHz LNA Design with Inductive Source Degeneration in 65 nm CMOS Technology

This paper presents source degenerated cascode 60 GHz Low Noise Amplifier (LNA) is modelled in ADS and its performance is measured by computing Noise Figure (NF) and gain from simulation waveforms. Parameters such as LNA linearity and stability is determined and designed to be within permissible limits. The designed LNA is optimized for its area with 30% reduction. The measured result of the designed LNA shows 19.48 dB gain, 4.7 dB NF and IIP3 of –10 dBm. The Figure of Merit (FoM) characterized as an element of the NF and IIP3 is 17, which is the best outcome among past LNAs.
