摘要：

To　solve　the　existing　problems　such　as　lower　quality　factor　and　inductance　value　in　common　active　inductor,　a　novel　cascode-grounded　active　inductor　circuit　topology　was　proposed.　The　Rf　is　added　and　the　RC　feedback　cascode　positive　feedback　is　formed　used　to　substantially　improve　equivalent　inductance　and　quality-factor.　This　novel　active　inductor　was　implemented　by　using　a　TSMC　0.35-μm　3P4M　SiGe　BiCMOS　technology,　which　demonstrates　a　maximum　quality　factor　of　2563　with　an　inductance　of　3.165nH　at　4.3GHz.　©　2012　IEEE.
