How to Model the Near-to-the-Carrier Regime and the Lower Knee Frequency of Real RF Oscillators

الملخص EN

Numerous empirical data demonstrate that real noisy RF oscillators are affected by power-law phase noise.

However, until recently, the robust analytic modeling of the deep-into-the-carrier spectral regime of RF oscillators was intangible due to the infinities involved in the relevant power-law regions.

In this letter we demonstrate how recent advances in oscillator spectral modeling can be applied to extrapolate the near-to-the-carrier regime as well as estimate the oscillator lower knee frequency of transition between the deep-into-the-carrier regime and the power-law regions of real RF oscillators.
