AB  - A  low  power,  low  phase  noise  and  wide  tuning    range    4GHz    LC-based    voltage    controlled    oscillator  (VCO)  to  be  used  in  a  phase  locked  loop  for  neutrino  experiments  is  presented.  The  design  process  should consider the limitations on the maximum tolerable jitter  of  the  clock  that  is  generated  in  the  PLL.  The  presented  structure  consists  of  VCO  block  followed  by  two frequency dividers. To achieve a linear characteristic over  a  wide  frequency  range,  the  VCO  uses  NMOS  varactors   to   control   the   frequency.   The   circuit   is   fabricated  in  a TSMC  65nm  CMOS  technology.  The  power  consumption  from  1.2V  power  supply  excluding  50Ω buffer stage equals to 6.9mW. Measurement results provide -94dBc/Hz phase noise at 1MHz offset frequency from  1GHz  carrier  frequency.  The  circuit  features  a  tuning  range  of  360MHz  at  the  output  of  dividers  for  a control voltage range from 0 to 0.8V.
