摘要：

Based　on　gyrator-C　principle,　a　novel　active　inductor　with　high　self-resonance　frequency,　high　Q　factor　and　independent　adjustment　of　inductance　is　proposed　in　this　paper.　A　varactor　is　added　in　parallel　with　the　positive　transconductor　to　improve　the　tunable　range　of　inductance.　A　tunable　resistor　between　positive　transconductor　and　negative　transconductor　is　used　to　generate　negative　resistance,　thus　enhance　the　Q　factor.　Furthermore,　a　feedback　capacitor　is　also　employed　not　only　to　generate　negative　conductance　for　enhancing　the　Q　factor,　but　also　to　provide　negative　capacitance　for　achieving　high　self-resonance　frequency.　The　results　show　that　the　self-resonance　frequency　is　up　to　12GHz,　the　peak　Q　factor　is　more　than　1300.　The　peak　inductance　can　be　adjusted　significantly　between　25.1nH-84.8nH　with　the　tuning　range　of　108.6%,　whereas　the　variation　of　the　peak　Q　factor　is　only　1.6%.　©　2019　IEEE.
