Abstract :
In this paper, we present a novel low power voltage-controlled-oscillator (VCO) based on bandwidth enhancement technique. The enhanced bandwidth allowed the VCO to achieve steep output waveform resulting in improved phase noise. The VCO was fabricated in 0.13 μm standard CMOS process having 6 layers of copper metallization. The oscillation frequency ranged from 4.48 to 4.82 GHz with a turning range of 7.5%. The measured phase noise of the VCO was -119 dBc/Hz at 1 MHz offset under 4.2 mW power consumption.
