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.
This paper proposes a 60 GHz quadrature PLL frequency synthesizer for the IEEE802.15.3c with wide tuning range and low phase noise. The synthesizer is constructed using a 20 GHz PLL that is coupled with a Quadrature Injection Locked Oscillator (QILO) as a frequency tripler to generate the 60 GHz signal. The 20 GHz PLL generates a signal with a phase noise that is lower than dBc/Hz using tail...
