Hello, I have built and amplifier which acts exactly like in the open loop behavior where the gain reduces as the bandwidth increases by the LOOP GAIN factor.(As shown bellow)
However when i calculated the LOOP GAIN i should have OPENLOOP=CLOSED_LOOP+Loop_gain.
Then i remmembered what Andrew said that by removing the loop we change the conditions .
Is there a way in STB to plot OPEN LOOP GAIN and Closed Loop Gain?
So in the same situation i will get OPENLOOP=CLOSED_LOOP+Loop_gain.
I have no idea what you mean by closed loop gain and open loop gain. The loop gain is the loop gain; if the loop was open, it wouldn't be loop gain any more. Stability analysis measures the loop gain - that's it.
I don't know what you're trying to do here as it doesn't make sense (again).
i understand.Thank you very much.
