Abstract

In this paperâ, âan inductor-lessâ, âhigh frequency tuning range and low power CMOS voltage controlled oscillator (VCO) is presentedâ. âThe VCO can be implemented in 0.18 µm CMOSâ, âwith 1.8 V supply voltageâ. âBy using a novel structureâ, âa high frequency tuning rangeâ, âlow phase noise and low power consumption VCOâ, âis obtainedâ. âIn order to increase the frequency tuning rangeâ, âan active inductor is usedâ. âIn additionâ, âdeep triode region transistors are employed to enhance the swing of the output voltageâ. âBy using the results of simulation with HSPISE softwareâ, âthe tuning rangeâ, âphase noise and power consumption are 5.49-9.6 GHzâ, -â146 dBc/Hz and 5.99 mWâ, ârespectivelyâ.
