01 - The Non-Inverting Op-Amp (Amplifier) Circuit 

This guy is the absolute best teacher I've ever learned from.

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!

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!

Absolute legend. This makes the inverting and non-inverting concept so much easier to understand. You’re the best

Brilliant teacher - detailed and logical explanations - makes it look so simple. 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-

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.

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!!

Man you really know how to speak to the people… the best of the best

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!

Finally a lecture that closely matches my teachers notes... thanks a lot for the easy explanation of the op amps

I love how these great teachers give us these lessons for free. TY TY tY

This class is a masterpiece. Thank you!

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

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

Yes He is the absolute best teacher . No doubt about that

A very clear and concise explanation

Your teaching method is really Amazing.

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

The best tutor I've seen in life

Well explained sir, thank you for your explanation.

Very straight forward. Thank you

This was a great tutorial. Well done, dude.

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

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

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!

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?

thank you very much it is very good lecture. clear and easy.

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

Brilliant lecture!

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

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.

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?

Great explanation.

Fully understand that topic thanks sir

감사합니다.

Pete Repete - how do I configure a noninv. opamp to less than 1 in gain?? ;)

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

Great explanation thank you

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?

Thanks Guru Ji.

Hi I need the link to the video on inverting op-amp. Thanks

amazing teacher !!

Legend, op-amps now make sense :))

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

Really helpful...

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

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.

worth appreciating

You are the best👍💯

Wonderful.

thnk u soo much!! God bless u

Thank you so much

It gets difficult to track down the next video from your channel. Could you help on that, sir? @math and science

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

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?

Respect from Bangladesh

Can I use it on stabilizer

waiting for more videos in this section please

Thank you sir

Where is the next video of this one !???

anybody has this full course? can you send it to me

Wish you wired circuit clearly and took electrical measurements to clarify everything

thanks sir

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.

has the inverting op amp been deleted?

I en ideek op.amp er inngangene U1 og U2 lik (U1=u2). Det er ikke noe strøm som går gjennom selve op.ampen

Thank u now i understand

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...

He is well explained to dummy like me💕

He is so underrated

nice

Which grades

Sir need further videos on operations of OP-Amp.

This type of explanation is said to be real. Explanation

I should pay this guy my tuition not the uni

Rg isn’t in the textbook for me.🤔

i think u shld clearly label the earth

Translate to Indonesian 🙏, i'm so not understand

tidak mengerti bahasanya tapi paham penjelasannya

These are great videos. The instructor has a web site where he charges $ for these ( monthly or yearly) . I wonder why these are here for free? Are these legit? Or did someone post and ripping him off?

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

so hard

6+ min of intro?!

bro called me a monkey :(

Excellent letcures But toooo much talkative Please brief little bit

Why do you make everything so complicated? Remember KISS? All the gibberish is useless.

Thanks 🙏👍💯😊

Very clearly explained. Thank you Sir
