How do i properly set up a colpitts oscillator?

  1. Nov 14, 2007 #1
    i need a colpitts oscillator in this circuit i am building but i am having a very hard time finding an oscillator design that work and figure out what values i need.

    Can anybody give some suggestions on colpitts oscillator designs? I am looking for an oscillation frequency below 100 kHz. Should I use an Op-Amp, transistor, or JFET to make the oscillator? Also, I know how to pick the LC values for the tank circuit in order to get my desired oscillation frequency, but I do not know how to properly bias the rest of the circuit to get oscillations.

    Any help would be much appreciated.
