A 3.23dB Average NF and 2.32dB Minimum NF V-/E-Band Common-Gate/Common-Source Joint-Feeding LNA with Three-Line Coupler Input Matching for Simultaneous Noise/Power Matching

The proposed and implemented V/E-band LNA in 22nm CMOS FDSOI achieves measured average noise figure (NF) of 2.32dB and avg.13.8GHz (60.6-74.4GHz) 3dB bandwidth over 5 samples. It utilized a three-line coupler to provide wideband simultaneous noise and power matching and gm boost. This LNA design provides a compact chip area with moderate power consumption and extremely low NF, which together can support the future backhaul system and fixed wireless networks of 5G and beyond-5G communication.
