A novel resonant circuit consisting of transformer-based switched variable inductors and switched accumulationMOS (AMOS) varactors is proposed to realize an ultrawide tuning range voltage-controlledoscillator (VCO). The VCO IC is designed and fabricated using 0.11 μm CMOS technology and fully evaluated on-wafer. The VCO exhibits a frequency tuning range as high as 92.6% spanning from 1.20 GHz to 3.27 GHz at an operation voltage of 1.5V. The measured phase noise of -120 dBc/Hz at 1MHz offset from the 3.1 GHz carrier is obtained.
