We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

Consider the following illustration in Figure 1 of what we shall see is an oscillator, specifically, a Colpitts oscillator. Figure 1 The Colpitts oscillator where the passive components are arranged ...

A. Determine the frequency for the oscillator of the given circuit. Assume there is negligible loading on the feedback circuit and that its Q is greater than 10. B. Find the frequency if the ...
