Thank you so much! I hope i can handle with this questionWell, the KVL for the output node is
Vcc - Ic*Rc - Vce = 0
And good luck with this "strange" question.

Thank you so much! I am new in this course and my calculations are so short to share i am at the beginning so that it would be great to learn where should i begin if you can helpWelcome to AAC!
We don't know what you've been studying/taught. Show us how you would do the calculation for one of the required base voltages so we can see what technique you've been taught to employ and where you're having difficulty.
You should go to your instructor or teaching assistant so they can instruct you in how to do it the way they intended.I am new in this course and my calculations are so short to share i am at the beginning so that it would be great to learn where should i begin if you can help
I will do it so. Thank you for your repliesYou should go to your instructor or teaching assistant so they can instruct you in how to do it the way they intended.
It's been decades since I thought about transistor theory at that level because, in the real world, we (at least I) rarely need to use models for our designs.
Since you were given reverse saturation current and temperature and were told to ignore Vbe and beta variation, there must be something specific you're supposed to learn from this problem.
Are you familiar with this equation? Because it looks like you will need it.Thank you so much! I hope i can handle with this question
Yes i calculated the Ic as 9.04 microampere by taking VBE = 0.7V. And the other equation from the base part will be Vin-VBE=0 i guess. Can i say Vout equals to Vcc-Ic×Rc?Are you familiar with this equation? Because it looks like you will need it.
Ic = Is*e^(Vbe/Vt)

Yes you can.Can i say Vout equals to Vcc-Ic×Rc?
It seems like i can solve this question from there . Thank you so much for your replies!Yes you can.
Hi, we havent come to the amplifiers yet. And our instructor didnt solve questions like this before. I thought i can solve this question but i couldnt compounded it with saturation. If i say Vcc-Ic×Rc=Vout then how should i plot Vout and Vin?Hi,
Because they give some restrictions and Beta and Vsat i would think this is just a more or less amplifier problem with an input and output, and watch for one restriction on the output voltage, that's all.

Oh, was it that simple yes i understand now. Thank you for your repliesif the voltage every goes below 0.2v you simply call it 0.2v. Does that make sense to you?
Looks more like a voltage-controlled current-source to me, as per the equation in post #9.they are allowing you to use the current controlled current source model for the transistor

Unless the β value is just a red herring and is not needed in the calculation.Now that i've read it over again though, i see that this looks like they want the student to use the single diode transistor model.
