Abstract
We have developed phase noise models for ring oscillators and applied our theoretical analysis to an example design of a ring oscillator. In a real system, a VCO is rarely used as a stand-alone component, because its output frequency is not well controlled. It is usually used in a PLL so that its output frequency is digitally controlled and its close-in phase noise is significantly suppressed by the PLL feedback loop.
