Abstract :
A single port 1/f model is examined of a crystal oscillator combined with a resonator and an equivalent negative resistance of amplifier. Intrinsic 1/f flicker fluctuations of resonator and amplifier amplitude and phase are converted to the oscillator amplitude and phase, and the proper transformation coefficients are applied. An analysis of the oscillator phase power spectral density is provided in detail for the particular case of a resonator excited in oscillator at various frequencies. Conformity with the Leeson´s model is shown.
