Two 130nm CMOS VCOs with ferroelectric varactors are presented. The cross-coupled VCO-cores are flip-chip mounted on silicon carriers with integrated inductors and tunable ferroelectric varactors. The output frequency of the first VCO is tunable from 23.4 GHz to 26.1 GHz, corresponding to a tuning range of 11 %. The phase noise of this VCO, tuned to its center frequency, measures -117 dBC/Hz at 1 MHz offset and the power consumption is 18 mW. The second VCO is tunable from 25.8 GHz to 30.5 GHz, corresponding to a tuning range of 17 %. The phase noise at center frequency for this design measures -109 dBc/Hz and the power consumption is 5.3 mW.
