Thanks for this huge amount of good detailed information about the diff amp. My task is to build a diff amp with two P-channel as a load. How can I make an internal current source with two N-channel and one P-channel?
You need to have a DC Signal (Common Mode Signal) in order for current to flow. The common mode signal essentially turns on both FETs and turns them both on the same degree. Adding small AC input signals on top of that will ensure that there is a differential output at the drains of the transistors.
The polarity of Vo1 and Vo2 is different for only differential input. For the common mode input, it is same. And that's why for the common mode input, the differential output Vo1 - Vo2 is zero.
If true differential input signal is not readily available, then the differential input signal can be applied at only side. And still, it is possible to obtain the similar result. For more info check this simulation. www.multisim.com/content/WfWiSqnoRcTvjcpFrX3KL9/mos-differential-amplifier/ Here, DC voltage on both side acts like a common mode input to both terminals. While, 10 mV input signal is applied at only one input. The Differential gain is 4. So, differential output Vo1 - Vo2 is 40 mV.
Thanks for your good illustration, Could you recommend me good books in this area to study.? And, because I am working in RFIC circuits, do you have any contact information, I can contact you and discuss more about anything that I need to discuss, If you don't mind 😍😍

You are single-handedly making me pass my analog electronics course
What my lecturer and friends have been teaching for months,I actually just understood in this video. Thank you 😊
seriously, i really like this kind of channel which explains in detail and clearly.
One of the best diff amp lectures on TH-cam
It was amazing, loved the explanation and how you proceeded with the topics and then build up upon them
Great one, even @the university we didn't get such great explanation.
true
Thank you so much sir for taking the time to give such an excellent explanation.
I was about to refer for this video and got it in time.😄
Wonderful Content
Please make a dedicated video on Lockin Amplifier
Cheers✨✨
will consider it.
7:48 why in this part we divided the differential input by 2 isnt the differential input of both vin1-vin2?
I have got the same question!
Thanks for this huge amount of good detailed information about the diff amp. My task is to build a diff amp with two P-channel as a load. How can I make an internal current source with two N-channel and one P-channel?
Very well explained 👍👍
Think. for. such. a. good. teaching
Very clear explanation.
You are awesome. Thanks bro.
Sir, can you explain the microcontroler program?? Please sir.
Sir can you please inform about the book you are using?
nice work , man
Well done
Best channel
You have many playlists, in what order should I watch them? (from 0 to %100)
You can start with basic electronics and network analysis playlist. And then you can refer other playlists.( Diode, BJT and MOSFET)
@@ALLABOUTELECTRONICS thank you
Very nice explanation
what is the advantage of common mode signal input then , if the differential output is 0 all the time. where it is used ?
You need to have a DC Signal (Common Mode Signal) in order for current to flow. The common mode signal essentially turns on both FETs and turns them both on the same degree. Adding small AC input signals on top of that will ensure that there is a differential output at the drains of the transistors.
Nice explanation bro... But my all students asked for "ITI-ELECTRONICS" MATHES Problems please provide electronics caliculations
How is it that Vo1 and Vo2 have different polarity when it connected the exact same way?
The polarity of Vo1 and Vo2 is different for only differential input. For the common mode input, it is same. And that's why for the common mode input, the differential output Vo1 - Vo2 is zero.
Can i get this slides ,please ?
THANK YOU
Thanks
Thankyou sir
Superb
How to split the signal that need to be amplified to vin(1) and vin(2)
If true differential input signal is not readily available, then the differential input signal can be applied at only side. And still, it is possible to obtain the similar result.

Here, DC voltage on both side acts like a common mode input to both terminals.
While, 10 mV input signal is applied at only one input. The Differential gain is 4.
So, differential output Vo1 - Vo2 is 40 mV.
@@ALLABOUTELECTRONICS Thank you, but is it possible to generate differential signal out of single ended signal?
Yes, with the help of a transformer, it is possible to generate the differential signal from a single ended signal.
Good content but poor way of presentation, so hard to focus with that accent and tone of speaking, always fall asleep
Then go to bed 😪 not on comment section
In which accent people should speak English? Come on....
I can't understand your accent, please put subtitles below to the screen
Very difficult to understand ..terrible accent.
Thanks for your good illustration,
Could you recommend me good books in this area to study.?
And, because I am working in RFIC circuits, do you have any contact information, I can contact you and discuss more about anything that I need to discuss, If you don't mind 😍😍
