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 low noise amplifier (LNA) in 22nm CMOS FDSOI covering 3dB bandwidth of 60.6 to 74.4GHz. It achieves a measured average noise figure (NF) of 3.23dB averaged over the 3dB bandwidth and over 5 samples. Moreover, it records a measured averaged minimum NF of 2.32dB at 65GHz over 5 samples. It utilizes a three-line coupler to provide wide-band simultaneous noise and power matching and trans-conductance (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.
