You explain things so logically. My teacher on the other hand, I don't understand half of what he is yammering on about in my 2 hr lectures. Thank you!!
This is the only explanation of summing amplifiers I’ve found so far that I can actually use, now I just need to find something that helps me understand non inverting summing amplifiers.
Thank you so much for this video and taking me out of my misery! You are great at explaining electronic math. I also appreciate the video has no background music. Thank you 😊
Can you please do a final review for physics 203 & electrical circuits! Really appreciate all the work you put through, been a supporter since gen chem days
Could also do Superposition, vO = v01 + v02 + v03 and find each individual output voltage by shorting the other input voltages, and then come up with equation that way
Hi, you probally already found the answer, but for anyone else wondering what you would do in this case. You would put an inverting amplifier with a gain of 1 after the summing amplifier, this way the output of the summing amplifier is inverted again (making it a positive output) Take a look at the a-level electronic ebooks, they are great for learning the basics such as opamps: resource.download.wjec.co.uk/vtc/2016-17/16-17_1-9/gce-electronics-book-chapter-4.pdf
You can work things out with Kirchhoff's current and voltage laws, along with the approximations that there is negligible current going into the inputs of an op-amp and there is a negligible voltage difference between the inputs.
I've tried building and simulating this kind op circuit, but the result is not as expected. I'm using the same resistors (10k) and testing simply with 2V+3V right now. If the OP-amp is supplied with ground on the negative rail, the result is 0,1V and if the supply is +12 -12 V, the result is 11,98V. What am I doing wrong?
master JG I love your Video for a long time . can you give me a youtube lesson of about how to calculation R2R ladder and Flash ADC ? Please Please Please
It was just a different way of saying all the fractions share a common denominator. Put objectively confusingly: x(1/y + 2/y + 3/y) =x/y * (1+2+3) =x/y * (6) =6x/y OR x(1/y + 2/y + 3/y) =x(6/y) =6x/y
The output is just a 180 degree phase shift of the input. So negative input becomes positive output. Since we're talking alternating current - at the next period the input will become positive anyway, and the output will become negative

Does this guy know EVERYTHINGGG?????
Fr, I wasn't expecting to show up when I was looking for help. He even helped with random stuff like economics and coding😂
😂😂they a group of geniuses using a single auto tuned vocal
@@HboojyWoah really? Dude is a monster wtf lmao
him and professor Dave getting me through school ngl

These couldn't have been done at a better time, thank you.
He's just brilliant in everything!

how are you doing a better job than the teachers we pay
That is sum amazing information right there; your videos are phenomenal!
Wow,this is cool ,well explanatory.......good job
So helpful and clear. Thank you.
sometimes i forget thjat all these principles actually exist in real life
Helpful content.
Great video!
Thank you so much now i can get through the TCAP practice cause it will be on the test § Thank You §
yaY
How did your test go?
Could also do Superposition, vO = v01 + v02 + v03
and find each individual output voltage by shorting the other input voltages, and then come up with equation that way
GREAT Video!!! As always :D
One question...if one input voltage is negative, do I use the - sign in the equation?
The fucking goat has saved me again
Good job .
What if we want a positive output? Should we use the non-inverting input then?

This is for Indian exam jee IIT
Vibhav Srivastava amplifier is for design purposes of electronic devices ok its not in 12 th syllabus its included in engineering🤔🤔🤔🤔🤔
@@for1lakhnosubcriber1lakhrs89 thanks sir
So what exactly is the physical nature of the amplifier represented by the triangle symbol?
kindly add the link of playlist in the descirption
percfect video
I'm looking for how to do the "carry one" in the case the total doesn't fit the maximum voltage.
Thanks for the crux
sir we are adding another resistor at R2 in vertical direction .then what is vout
You can work things out with Kirchhoff's current and voltage laws, along with the approximations that there is negligible current going into the inputs of an op-amp and there is a negligible voltage difference between the inputs.
how do you know what supply voltages V+ and V- to use for a summing amplifier? Thanks in advance
You look on the datasheet.
Is it possible that the inputs are connected to the ground?
Thnks teacher

What if we use non inverting amplifier?
I think I know why I need to know this but, truth to tell, I'm not sure.
Why did you factor out the 10k resistor towards the end of the video?
It was just a different way of saying all the fractions share a common denominator. Put objectively confusingly:
x(1/y + 2/y + 3/y)
=x/y * (1+2+3)
=x/y * (6)
=6x/y
OR
x(1/y + 2/y + 3/y)
=x(6/y)
=6x/y
If all the input voltages are negative then what will be the output
If it is a inverting op amp (the voltages enter the negative terminal) then it will change the sign to positive
The output is just a 180 degree phase shift of the input. So negative input becomes positive output. Since we're talking alternating current - at the next period the input will become positive anyway, and the output will become negative
how to calculate output current for summing amplifiers?
Is there anything you don't know
I love you 💕💕💕
3:27 should be -9v
toward the end i think you made an error. its 600 VOLTS not milivolts
