A　new　common-gate　(CG)　low-noise　amplifier　(LNA)　with　a　passive　gm-boost　network　(PGBN)　is　proposed　in　this　work.　With　a　much　bigger　gm-boost　amplification　coefficient　introduced　by　the　PGBN,　the　fixed　noise　reduction　coefficient　(with　the　max　value　to　be　1)　for　the　traditional　capacitor-cross-coupled　CG　LNA　is　broken.　As　a　result,　the　noise　figure　(NF)　can　be　further　reduced.　Moreover,　the　power　consumption　can　also　be　greatly　reduced　simultaneously.　The　proposed　LNA　is　of　great　interest　for　low-power　fully　integrated　wireless　communication　receiver　with　relative　high　NF　requirement,　which　is　designed　in　a　TSMC　0.18　mu　m　process.　The　experimental　simulation　results　show　the　proposed　LNA　achieves　7.6　dB　power　gain,　a　NF　of　1.3　dB,　good　input/output　matching　with　the　S11　and　S22　both　less　than　-40　dB,　and　the　IIP3　is　measured　to　be　-11.8　dB.　The　LNA　also　demonstrate　an　ultra-low　power　consumption　of　0.67　mW　with　a　1.8　V　power　supply,　which　is　quite　suitable　for　＂Green＂　power　consumption　applications.
