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

- The small signal analysis turns out to be:

I am trying to find the AC analysis of a BJT Hartley oscillator but I cannot continue . How do I find the voltage again.When no feedback is there , 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 blury.-

Finding voltage gain of Hartley oscillator
I am trying to find the AC analysis of a BJT Hartley oscillator but I cannot continue . How do I find the voltage again.When no feedback is there , 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 blury. Also I am not sure if I have done the AC analysis correctly.Any help is appreciated!
