How to determine the oscillation frequency of a multiple resonance circuit?

Hardware design
November 20, 2020 by Kareena 1468

If I have a self-oscillating oscillator with multiple resonances, what are the criteria for judging the oscillation frequency? For example, this circuit,

There are two resonance frequencies in high coupling, such as the resonance frequency f≈f0/√(1±k).


How to calculate the oscillation frequency of such a circuit?

Use Bode diagram.

Still have to use Bode plot analysis.

The oscillator can oscillate at two different frequencies at the same time, which is called intermittent oscillation.
