An ultra-low power current reused CMOS low noise amplifier for x-band space application
This paper presents fully integrated ultra-low power CMOS low noise amplifier (LNA) for x-band space application by employing current reused technique. It also operates in subthreshold region to reduce power consumption significantly. The state-of-art low noise amplifier targets 10.8 GHz for x-band frequency in advanced conventional 65-nm CMOS technologies. It achieves power gain (S21) of 10 dB, noise figure (NF) of 2.9 dB, input-referred third-order intercept point (IIP3) of -9 dBm, while consumes only 125 uA and operates with supply voltage of 0.6 V which results in total power consumption of less than 80 uW.
