摘要：

A　UWB　LNA　(low　noise　amplifier)　based　on　0.35m　SiGe　BiCMOS　technology　is　presented　in　this　paper.　This　LNA　adopts　a　resistance　feedback　topology　to　optimize　the　gain　and　noise　figure.　The　serial　inductance　at　the　base　is　used　to　matching　input　impedance　and　decreasing　group　delay　variation.　The　simulation　results　indicate　that　the　gain　of　LNA　reaches　12.5dB　with　the　variation　of　1.9dB　and　the　power　consuming　is　6.3mW　in　full　band　from　3.1GHz　to　10.6GHz.　This　SiGe　UWB　LNA　exhibits　less　than　5ps　group　delay　variation　and　less　than　3.85dB　NF　over　the　entire　band.　©　2008　IEEE.
