Oh sorry, I have a mistake with the picture 1.The first circuit does not have an emitter follower.
The second circuit has an emitter follower in the second stage.
The capacitors you have circled in red change the response at higher frequencies.
Is this homework?
In that case, moved to Homework Help.Oh sorry, I have a mistake with the picture 1.
Yes this is my homework
Nice...So in the first circuit, he's trying to invert the signal twice..Although why use current source as input? Isn't Rout of current high?Hi everybody,
I'm meeting a trouble with Emitter-Follower Amplifier circuit. That is in two attached pictures.
What is the meaning of two capacitors that I highlight by the red circle?
As well as, what is the "self-trigger" in Amplifier circuit?
Thank you!

The low frequency corner for the transition from the DC gain value to the AC gain value is determined the the R4C time-constant.
Below the R4C corner frequency it series impedance starts increasing and the gain is eventually determined by the value of R8 at DC.Don't understand
