Two V-band low-noise amplifiers (LNAs) with excellent linearity and noise figure (NF) using 90-nm CMOS technology are demonstrated in this paper, employing parasitic-insensitive linearization topologies, i.e., cascode and common source, for comparative purposes. To improve the linearity without deteriorating the NF, the 54-69-GHz cascode LNA is linearized by the body-biased post-distortion, and the 58-65-GHz common-source LNA is linearized by the distributed derivative superposition. Using these parasitic-insensitive linearization methods at millimeter-wave frequency, the cascode LNA can achieve an IIP3 of 11 dBm and an NF of 3.78 dB at 68.5 GHz with a gain of 13.2 dB and 14.4-mW dc power. The common-source LNA has an IIP3 of 0 dBm and an NF of 4.1 dB at 64.5 GHz with a gain of 11.3 dB and 10.8-mW dc power. To the best of our knowledge, the proposed cascode LNA has up to 11-dBm IIP3 performance and the highest figure-of-merit of 156.2, among all reported V -band LNAs.
