Abstract
This paper presents a linearized wideband LNA in 65-nm CMOS for 28-GHz 5G applications. The prototype LNA has three common-source stages coupled by transformers. The large-signal multigate transistor (MGTR) technique is used in the last stage, utilizing auxiliary transistors to suppress the third-order distortion with little additional power consumption. Layout simulation results shows the prototype LNA achieves -5.6 to 3.8 dBm IIP3, -16.8 to -13.9 dBm IP 1dB , 20-23 dB gain, 3.4-4.4 dB NF over 22-32.7 GHz and consumes 43.6 mW from a 1 V supply.
