Low Phase Noise LC VCO
This paper presents a low phase noise LC VCO applied in PLL.Through inductor optimization,the circuit has a low phase noise and a wide tuning range with NMOS varactor.Simulation results with CSMC0.5μm CMOS process show that the tuning rang is 2.02GHz~2.5GHz and the phase noise is-175dBc/Hz at 500MHz offset with a 3.3V power supply.
