2009 IEEE Journal of Solid-State Circuits  
It consumes 4.2 mA from a 1.8 V supply and occupies an active area of 0.4 0.45 mm 2 . With a frequency division ratio of 40, the in-band phase noise at 200 kHz offset is measured to be 126 dBc/Hz.  ...  Moreover, no frequency divider is needed in the locked state and hence divider noise and power can be eliminated.  ...  Wienk and H. de Vries, for practical assistance, and X.
