Does anyone know how to find the resonant frequency for the attached circuit in terms of C's and L's?

Is the formula on the page same as resonant frequency?
Hey Matt, we never went over this in class and I couldn't find any example in our book, or online. So could you tell me how to derive it, I have no idea where to start with this. And I am also confused how the small signal circuit is supposed to help me with the question either.This sounds an awful lot like a homework question. Why don't you attempt it yourself first, and then we can look at it and see what you might need touching up on?
Regards,
Matt
That's a colpitts oscillator. Is that the same thing as the question?Here you can find lecture notes on this subject.

That is the point of the homework. You have the start and you have the end, it is your job to connect the two.That's a colpitts oscillator. Is that the same thing as the question?
Also I couldn't really find anything in the notes where the resonant frequency is derived, it's kind of just given there. Could you explain how that works?
Yeah I can't figure out how to make that connection. Could you tell me how to?That is the point of the homework. You have the start and you have the end, it is your job to connect the two.
From googling, Clapp Oscillator is a Colpitts type oscillator.
Here you have. Now all you need to do is to w rite the transfer function for feedback and solve for ωo to make the imaginary part of the denominator = 0Yeah I can't figure out how to make that connection. Could you tell me how to?
