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

    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,

    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.

    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.

    Yeah I can't figure out how to make that connection. Could you tell me how to?

    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 = 0

    Is there an example I could look at to see the steps to find the resonant frequency
