Phase-noise mechanisms in cross-coupled LC voltage-controlled oscillators (VCOs) are reviewed based on a physical understanding of reactive power imbalances in the tank and in the active part. These phenomena are proven to be the predominant phase-noise degradation mechanism in relatively low- and high-current operations. Based on this analysis, a technique to suppress these detrimental effects is developed and implemented in an LC VCO design. The measured results confirm the dependencies… CONTINUE READING
