A 120-GHz Sub-6 dB NF and 19 dB Gain Low Noise Amplifier in 22-nm FDSOI

This paper presents a 96 GHz - 123 GHz 3-stage low-noise amplifier (LNA) design based on transformer matching networks (TMNs) in 22-nm FDSOI technology. The LNA achieves 19 dB measured small signal gain, 5.3 dB of the noise figure (NF) at 120 GHz, the NF remains below 5.8 dB from 110 GHz to 123 GHz. The LNA consumes 31 mW DC power.
