Amplifier Configurations - Solid state Devices and Analog Circuits - Day 6, Part 3

[@BUPETA3351]

Thank you for yet another awesome video. It would have been great if you mentioned uses, and diferent advantages between the arrangements, such as output impedances. I hope you will address Sziklai and Darlington pairs. All the best.

Thank you, Sir, for this interesting tutorial video

[@carlosmejia8111]

I want to thank you for your excellent and educational videos. I am 73 years old and you are the best teacher I had in my life. As a civil engineer and electrician amateur I specially appreciate their quality and hteir easy understanding. Do yu have a logical order for them to be studied? When I order them by date the subjects jump without logic. I would be very nice to have an index for them. Thank you very much again from Colombia.

you are number 1👍🌹

[@prabakaranpalanivelu]

Thank you for the video tutorial sir

Quick question, how did the current jump to 9.5mA when we biased the transistor from +5V to 6V? Thank you

[@eitantal726]

on 5V, the transistor was not saturated, and limited the current. on 6V, it appears to be nearly saturated, no longer limiting the current. What's missing is a resistor network that determines how much current enters the base

[@ecananth477]

thank you sir. sir is it possible explain about differential amplifier.

[@Hexum064]

For the BJT Common Emitter, shouldn't that first part be 2.5v, not 3.5v? And then only a 2x amplification?

[@eitantal726]

Math error, yes. But what actually controls the amplification factor is the current limiter on the base, which is not shown

[@willieandersson]

Hey. Love your videos! Your a great teacher. Could you make a video and explain the ne5534, what the balance pins do and everything? When you check a regular micpreamp circuit they almost always have a small cap in parallel negative feedback resistor, why? And sometimes they put like a 100uf cap before the second resistor reaches ground. Thank you for you hard work! Willie from Sweden

Where would one expect to come across the common base configuration? It seems an ugly way to do something, so some benefits must clearly exist. Would you list some please?

[@SheikhN-bible-syndrome]

When i connect to the output capacitor to the emitter I get extremely low output however if I connected to the collector I get much higher output why is that?

[@dany67230]

Real circuit ?

I am really enjoying your vids, so 1 thing disappoints me a bit. My mental arithmetic is pretty fair, and 7.5V from 10 is 2.5, not 3.5. This mattered as that error formed the part of other calculations. Sure, I got the point, but its still disconcerting. In your amp design vid you described 10mv as 0.1V instead of 0.01V and so derived 10mv plus 0.7V as 7.1V instead of 7.01V. Again, I understood what you were doing, but your calcs were now wrong in a few other places when you used 7.1V. I usually criticise calculator use for simple stuff, but please start using one - accuracy here matters in these classes. I apologise to you again, your classes are brilliant and I'm getting so much from them. Criticising is the last thing i want to do. These classes are brilliant. But sadly, these things scream at me. I'm much faster AND correct, usually, so notice these. If I'm wrong in either place (I kinda hope i am), please show what I missed - am fully aware I could have misunderstood something.
