Abstract :
A 2 GHz CMOS VCO, employing noise cancellation to eliminate flicker noise up-conversion, has been fabricated in 0.35 mum CMOS. An overall phase noise reduction of 10 dB has been measured with the proposed technique, and phase noise of -121.6 dBc/Hz@500 kHz offset has been achieved. The VCO core consumes 2.8 mA under 2.4V supply and occupies an area of 0.7 mmtimes0.8 mm. The proposed VCO measured FOM of -186 dBc/Hz.
