Abstract :
This paper proposes a 60GHz quadrature PLL frequency synthesizer that has a tuning range capable of covering the whole band specified by the IEEE802.15.3c with exceptional phase noise. The synthesizer is constructed using a 20GHz PLL that is coupled with a frequency tripler to generate the 60GHz signal. Both the 20GHz PLL and the ILO were fabricated using a 65nm CMOS process and measurement results show a phase noise of -96dBc/Hz at 60GHz while consuming 77.5mW from a 1.2V supply.
