Abstract— A low power VCO using active inductor is proposed resistance to reduce power consumption differing from other
to reduce the phase noise and to enlarge the tuning range conventional VCO using active inductor. We obtained lower
performance. It is implemented by um CMOS process. The power consumption than that of the conventional VCO. This
main idea of the proposed VCO is to replace the active circuit
of the conventional VCO with active inductors. This method can paper shows a VCO architecture that can achieve low phase
improve the phase noise performance of CMOS VCO by shifting noise, low power consumption and wide tuning range by
proper zero frequency of the active inductors. Additionally, it replacing the conventional active circuit with active inductor
can also improve the tuning range of the VCO because the with
