Design of Low-Power Sub-2.4 dB Mean NF 5G LNAs Using Forward Body Bias in 22 nm FDSOI

This article presents K/Ka-band low-noise-amplifiers (LNAs) for 5G front ends. The use of forward body bias (FBB) in fully depleted silicon-on-insulator (FDSOI) devices is studied and utilized to improve the LNA performance under reduced supply voltage and dc power (P _dc ). Design procedures targeting high linearity, low noise, and high gain are...
