Comments on Finding voltage gain of Hartley oscillator

Finding voltage gain of Hartley oscillator

+0
−0

I am trying to find the AC analysis of a BJT Hartley oscillator but I cannot continue. How do I find the voltage gain? When no feedback is there, we just find the output resistance and the current inside the output resistance and find the input resistance and the current inside the input resistance but know that there is feedback things become blurry.

Also, I am not sure if I have done the AC analysis correctly.Any help is appreciated!

1st EDIT:

I have tried to solve the circuit and I have correct some of my mistakes : The small signal analysis turns out to be:

G is the the closed loop gain.Is that correct?

Your original diagrams were already too small to read easily. Your new diagrams are worse. You really should be able to see that for yourself. The problem seems to be that you are trying to cram too much stuff into pictures horizontally. Keep in mind that any picture you post will be resized to about 640 pixels across. You really should resize your picture to 640 across before you post them. That way it's obvious what will be visible. If you need more detail, use more space vertically, or more pictures.
