Abstract :
This paper proposes a push-push 20 GHz VCO realized by a 10 GHz QVCO for a quadrature 60GHz Local Oscillator. The proposed VCO is implemented in a 65nm CMOS process. It achieves tuning range of 3.0 GHz from 16.3 to 19.3 GHz with a phase noise of -105 dBc/Hz at 1MHz offset. The power consumption of core oscillators is 7.5 mW and an FoM of -182 dBc/Hz is achieved.
