this is absolutely the best video for non inverting op amps

[@colesteele4821]

After a week of lecture from my professor I had no clue how to do op amps. Watching this 30 minute video now I feel confident in solving almost any! Thank you so much!

Awesome!

I agree with most of the other comments - this guy does an amazing job of explaining not only the math, but first describes how the circuit works. Once that is understood, the math is much easier to understand. Thank you so much for making the time to post this video. All the best to you and take care!

[@wwabete2009]

How does he really do it? Making maths and science so simple to understand!!!! This guy is more than a just a teacher! Every time I watch these videos, I just can't stop!!

THIS IS THE BEST VIDEO I MAY HAVE EVER WATCHED I WAS SMILING THROUGH THE ENTIRE VIDEO!

[@MrMatt23c]

Been looking for the reason that the +1 is disregarded in the gain formula for the inverting configuration, finally found my answer here explained perfectly. Thanks!

[@Th3Mafia]

amazing, how you have so much info about how/why things are assumed how things are measured while explaining this..... i appreciate the filling in of gaps.

[@dan_yamp]

This class is a masterpiece. Thank you!

I have been watching your videos and subscribed to your excellent website so that I could get through Uni- You are quite literally A SUPER HERO- an a massive massive THANK YOU- ...your Laplace lectures are invaluable-

[@nitdawg007]

A very clear and concise explanation

[@professorattiqurrehmanoffi205]

Your teaching method is really Amazing.

[@dalenassar9152]

THANKS!! Three things: 1) Why introduce Rg at all? 2) You didn't mention the advantage of the high impedance compared to the inverting amp 3) 23:00 I was anxious for you to say the gain could go to 0. Not just much lower...

[@mckanebullerlee3020]

Rg, I assume, is for smoothing ripples from source trigger signals (transients).

[@dikilhamusherpa6701]

You have a gifting to teach clearly and best, nice job, its cleared my doubt

[@MrArlenBrazill]

Thank you so much. My community college professor is trying to teach this and he's so lost. It's not really all that complicated is it?

[@guillaume6373]

Legend, op-amps now make sense :))

[@valkman761]

While working with ideal op-amps in college, I learned in real life that there's no such thing as ideal op-amp. For instance, v1 is not equal to v2 and i1 and i2 is not equal to zero. Makes big difference in embedded circuit design.

[@Sidhudalwindergmailcom]

Sir i am very exited to see wualified person's technical video. Please through some light in phase error in inverting and non inverting teminals. Thanks

[@TechSouls-wn6jc]

wonderful explanation sir need more numericals relevant to inverting and non inverting opamps

[@goofypettiger]

This was a great tutorial. Well done, dude.

[@TYGAMatt]

Very clearly explained. Thank you Sir

[@Imab1234]

Fantastic explanation, one of the best explanations of the op amp I've seen. I still don't understand how Rf and Rs are voltage dividers if its said that no current passes between the 2 terminals. If there's no voltage applied between the 2 terminals, how can there be a voltage drop on either resistor? If there's no voltage drop on any resistor (or at least Rg) what is the point of these resistors being in the circuit in the first place?

[@billguitarvin]

lmab1234 - so sorry this answer is 2 years after your question is asked. If I understand the non- inverting opamp, there is current flowing between Rs and Rf. The link to this video below shows it in this animated video. I believe it is using an AC signal, as the current is changing direction between Rs and Rf. kzbin.info/www/bejne/laCXhJadh7-nhKs

[@imranhossain8039]

Respect from Bangladesh

[@waynegram8907]

MATH and SCIENCE, Do you have any video lessons about how to bias transistors because there is multiple methods are how to biasing a transistor. Some use the HFE, some use the resistor ratios of RC and RE to get the gain, some use the datasheets IC current. If you want a gain of 5 you would have to base the RC and RE ratio and use that first as the biasing method. Others use the HFE to calculate the gain, so it gets confusing which method to use for biasing transistors. When looking at Resistor Ratios you can tell the gain of an op amp or transistor stage amplifier.

[@សំនាងខែ្មរ]

He is well explained to dummy like me💕

[@noorfalak6341]

What is the effect of sound signal if we use inverting amplifier for amplification?

[@frankstrasser6108]

What I’ve found from using op amps is for linearity they can’t even go near the rails or they saturate even unity gain ones

[@pierremaixant]

Well explained sir, thank you for your explanation.

[@nevis2769]

[@noorfalak6341]

9:24 why input is also grounded , the one applied to non inverting terminal?

[@mahdiabdulrahman8422]

Fully understand that topic thanks sir

[@AlexChen0905]

For the purple equation of 16:56, why is it not v1=v0(RsRf/(Rs+Rf))? If we use KCL on such a circuit, we get (v1-0)/Rs = (v0-v1)/Rf, and then we transform this equation into the equation above.

[@serapkiris1270]

Great explanation.

[@vangelova7443]

I was trying to find the video about the inverting op amp and I couldn't. I have some questions connected to inverting op amps, for example, if I have Uout and Uin and f = 1000 Hz, are there formulas with which I can find Rf and Rin? Thanks in advance!

[@KundabaheMoses]

You are the best👍💯

[@KareemMohamed-zo5zj]

amazing teacher !!

[@petedazer3381]

Why can’t you use two opamps , off the same AC input, one into the inverting input and the other into the non inverted input , and use this as a phase inverter before a push- pull power amp?

[@uiticus]

This virtual short between the 2 input terminals of the op amp applies only if there is a negative feedback on the op amp, right?

[@SpeedDeamon95]

Do you guys have videos over Circuits 2 with Laplace transform and Fourier analysis?

[@efearcan5199]

Great explanation thank you

[@noorfalak6341]

have you uploaded a video on transistor as a switch? if yes , link plz...

[@Shah66666]

[@joseriggio4366]

Exelent episode very clear, only one thing I can not figure out what is the function of Rg, thanks

[@princepaul7149]

The input impedance of a non inverting opamp is approximately equal to infinity,it has no function there

[@erfanmazaheri4203]

ok, if Vg is equal v2 ,so why we use Rg???does it use for noise or control current???

[@nagasai2364]

Why v1 is v0 times rs/sum and why not rf/sum??????

[@tommyponce2511]

babu might be a little late for the reply, but it’s because you want to know the voltage drop across Rs to know the value of V1, because V1 is the voltage drop across that resistor, so you multiply by Rs, and divide by the sum of both resistors
