Find feedback of circuit

+0
−3

I have this circuit:

I think that R3 acts like a feedback path from the output to the input.However I am not sure what will happen if I change the value from 100Ohms to lets say 1kOhms.

I have this image in mind:

and I know the open loop gain must be close to 1 since we have a common collector(and relatively big value resistors) but I dont have any idea what kind of feedback this circuit has.

What kind of feedback is there in this circuit?And which is the value of the feedback factor?

Explain how you think how the circuit works. In particular, I want to know what you think R3 does, and why it has the value it does.

Remember, we don't just answer homework questions here. We can help you thru the process or understanding a circuit, but that requires you to actively participate. You need to explain what you think is going on, what exactly you are stuck on, what you have tried, and why it didn't work. Show us that you're trying to learn, not just looking for a lazy way to get homework answers.
