Abstract :
In this paper, we propose a new voltage controlled oscillator (VCO) with a high oscillation frequency yet low power consumption. The oscillator which is a single stage circuit has a low phase noise due to reduced noise sources. To evaluate the performance parameters, the oscillator was simulated in a 0.18-μm standard CMOS process. The results show that the oscillation frequency of VCO may vary between 4.66-5.9 GHz. Also, the phase noise of the VCO at oscillation frequency of 5.6 GHz is -99.7 dBc at 1 MHz offset frequency. Also, the power consumption was 4.8 mW at the same oscillation frequency.
