Abstract
Methods are described that involve characterizing an oscillator's jitter or phase noise over a plurality of the oscillator's effective number of delay stages. The oscillator comprises a series of delay stages. Each one of the effective number of delay stages, if selected for the oscillator, describes a respective permissible range of inverter drive strengths that may be used within each delay stage of the oscillator to achieve a respective jitter or phase noise characteristic.
