Abstract :
A CMOS LC VCO in CSMC0.5mum is designed in this paper. To design the VCO some methods of optimization are proposed to reduce phase noise and ASITIC is used to optimize an on-chip integrated inductor. A NMOS varactor is applied here, which makes the circuit has a wide tuning range. In the paper, the supply voltage is 3.3 volts, oscillation frequency is 2.33 GHz.
