Design of 60 GHz GaAs LNA

Low-power 60 GHz low-noise amplifier (LNA) with a 9.379 dB peak gain and a 4.500 dB minimum NF is demonstrated in a GaAs Based technology. The LNA is composed of three stage of cascaded common-source stages with inductive degeneration technique. The 1^st stage of common-source given to the input stage for simultaneous noise and input matching. Also, the further stages is used for gain enhancement and interstage/output matching. This LNA consumes only 0.005 W from a 1 V supply.
