In this paper, novel two loop architecture of ring type voltage controlled oscillator (VCO) with low phase noise and low power dissipation in 0.18 μm CMOS technology is presented. To reduce phase noise and power dissipation, transistors in sub-feedback loop are operated in linear and cut off region and transistors in main loop of inverter are designed for fast switching with large voltage swing to minimize the switching current. The VCO has a frequency tuning range from 2.40 to 3.45GHz. The simulated result shows a phase noise of -107.56 dBc/Hz @ 1MHz offset from 2.6 GHz center frequency with a power consumption of 32 mW.
