CMOS-LC Voltage controlled Oscillator (VCO) has been designed and simulated using a simulation-based genetic optimization tool called AMIGO.. This VCO achieves a 25 % tuning range with a control voltage ranging from 0-3.3 V, while loads to a 2.4 GHz fully integrated oscillator using 0.35-mum CMOS technology. On-chip spirals are used in place of resistors to provide a low noise bias point to the varactors.. The On-chip spirals achieve more than1.17 nH of effective inductance while consuming a die area of 300 x 300 mum2. The simulated single -ended phase noise is -106 dBc/Hz at 600 KHz offset from a 2.4GHz carrier when the VCO core is drawing 4.77 mA from a 3.3 V supply.
