Hi Team,
As the title stated, how to build the simulation circuit?
I used this circuit, but I think it didn't produce the right results. Please give some guidance and thanks for your help!

And then here is this closed loop with those higher R's from the LG thread - little higher F-3dB than I expected but clearly very stable.
Hi Kai,
As for CFA, why do you choose a voltage source rather than a current source? If I want the closed loop gain, I think it's Zcl rather than Acl. Am I right? Please give some guidance. Thanks for your help!

Hi Michael,
I am confused about F-3dB. We regard F-3dB as BW, but in which picture can I observe the F-3dB? How to simulate that picture? In my view, the picture is the closed loop gain of CFA. When simulating, which source should I choose, voltage source or current source? Which terminal should I put the source, inverting terminal or none inverting terminal?
Thanks for your help! It's really helpful for me!

The current feedback amplifier is a voltage amplifier with internal current feedback, as I show above,
