I get really scared when I see amplifiers problems but when I follow instructions I can easily follow up and see what's happening. Basically feels like I am doing these problems with training wheels in a cycle. any tips as how not to get overwhelmed ? Also I paused the video at each and every step so I really enjoyed the process. Thank you.
Just practice more. And thoroughly go through theory. I used to give links of the related video tutorials in the description. Or you can check the playlist on the main channel. The more you practice, more it becomes easy for you.
@@allaboutelectronics-quiz Sorry to bother you again sir, I went through the BJT playlist here in your quiz channel and didnt find the video about exercises on bjt-bjt ,multistage amplifiers. If you find it, can you post the link here please. Sorry if I am troubling you!
ruclips.net/video/aaX29LUuW7s/видео.html I think there is one more. If I get it, I will post it over here. And if there isn't, I will post a quiz related to it very soon.
The early voltage is given in the question. If you are taking in general about BJT, then in the datasheet, it is mentioned either as early voltage or as output impedance or admittance.

Thank you, but what is the early voltage ? 4:45

Thankyou sir... This question was awesome.
i got to hand to you my friend you explained it really good
everything is crystal clear
thank you very much
Hi, Which tool you use for creating videos. It will be great help.
Excellent Tutorial my answer is (- 8.114)
We really thankful to u sir for providing such a great information about electronics...
Thanks 🤞
EXCELLENT 👌
Can we use Rc/Re as our gain for this circuit?
Here , we also have RL and Ro. so, we also need to consider them.
Will you do any exercises with multistage amplifiers? With Rs and RL if possible. Thank you very much!
I think I have already covered few problems on multistage amplifier. Please go through BJT playlist. You will get it.
@@allaboutelectronics-quiz okay thank you. I just started yesterday and wanted to confirm.

How to know which model to use
What is the unit of gm?
bro make a playslist of cmos solved quiz plzz
what is the input 10k resistor for? source impedance?
Yes, it is the series resistance connected with the source.
@@allaboutelectronics-quiz is there a way to know what value to use for the source impedance when designing a circuit?
ESE/IES
Mains paper 1 EE
Q6 (c)
2019
Thank you for solutions
Confirm your calculations sir... otherwise your delivery is best
Thanku so much aal dout are clear ❤️
i didnt get y did u included that emitter voltage in the KVL...cuz thats going out of loop...
It is still part of the loop. The only thing is, the current through emitter resistor is emitter current Ie.
Super sir
I didn't get how to change BJT into the small single model ? is there any special video on that topic?
Yes, there is a specific video for that on the main channel.
Here is the link: ruclips.net/video/i2t9GTAd2I0/видео.html
You can also go through the playlist of BJT for more insights:

Sir where is early voltage given?
The early voltage is given in the question. If you are taking in general about BJT, then in the datasheet, it is mentioned either as early voltage or as output impedance or admittance.
how did you get the vt?
Its given in the question. (Just look at the beginning of the video). If it is not given then you can find it using equation Vt = kT/ q.
By default we taken vt is 25 mv
Great
For changing the circuit to small signal. When do we use the models with ro?
When the channel length modulation parameter is given in the question or output resistance Ro is specifically mentioned in the question.
When Va (early effect is ignored) we say Va -> ∞ so ro =Va/Ic -> ∞ and we can ignore it as it is the same as an open circuit
Where is 100V come from
At 3.45 , how Vt = 25mv
It is given in the question. Please check the question at the beginning, you will get it.
@@allaboutelectronics-quiz sorry i didnt look
👍👍
Rth is 9.64 volts, obviously a typo error.
What is va here
It is the early voltage of BJT.
