Op Amp Theory and Design - Phil's Lab #53

[@ninefox344]

This single video could replace a few weeks of electrical engineering lecture and labs I went through years ago. Great work!

[@PhilsLab]

Thank you very much, I'm glad to hear that!

[@enginstud8852]

No it couldn’t, without these hours of lectures, you would be completely lost watching that video (even though it is awesome, but these things take time to understand and masterize)

[@mahudson3547]

Would have been great for revision! But as enginstud says you have to become fluent in the language and that takes time. Amazing that 50 years on, it is still all so familiar…

[@subutay1352]

Phil, you are simply amazing dude. I am the one who wants to be an embedded system engineer so I have interest for both hardware and software. You are the best . Notifications are open !

[@PhilsLab]

Thank you so much, Kamil!

[@denyskovalov2261]

I'm totally astonished why this channel has only 70k subscribers, considering so much insightful information in electronics

[@davidegandolfi25]

I thought I knew everything about opamps, but I was wrong! This is the first time I see someone really using discrete transistors instead of an IC 😥😎. Pretty impressive work for such a basic topic!! Thank you Phil for your efforts!

[@PhilsLab]

Thank you very much for your comment, Davide!

[@desaoaraujo]

Amazing content!!! I wish I had these videos 15 years ago while I was in engineering school!

[@Basetonic]

You make really nice Videos. I like how much information you do provide and how deep you go into details in this short amount of time.

[@PhilsLab]

Thank you, Johnny!

[@norm1124]

I try to understand the internals of am OpAmp since WEEKS, still not there. But maybe I will build a similar board, using this nice "dual transistors" in 6-pin packages to get as well matched pairs as possible. Thanks for all your gorgeous videos, you are one of my the leading advanced teachers here on KZbin.

[@stephencurtis2282]

Phil's a legend. Great work, Great explanations, nice matter of fact approach to some quite difficult subject matter. He makes it accessible in a way that we rarely see.

[@saucebosspl]

Excellent video. Hope you will cover stability of such an opamp soon. I'd love to see second order compensation methods like TMC. They are a great advantage of discrete opamps.

[@andymouse]

I come back to this periodically for a refresher because its wonderfully concise and digestible ...cheers.

[@PhilsLab]

Thank you, Andy - glad to hear that!

[@anotherlin]

Awesome video! Maybe you should do a dedicated series of videos regarding how to use opamps (the first half of this video), as your explanations are very clear and precise. And maybe some follow-up videos going deeper into the opamp of stages. For example, we hear about long tail pair difference amplifier but not much explanation about how they work.

[@briandohler8025]

World class content. Super simple implementation of concepts which are never presented so well in undergrad classes. Keep it up.

[@PhilsLab]

Thank you very much, Brian!

[@biswajit681]

Outstanding video Phill..hope you will cover stability issue with feedback in detailed in future... stability is the most difficult topic to deal with

[@PhilsLab]

Thank you very much! Yes, I'm planning on making a whole video dedicated to (negative) feedback.

[@mikevegeto1101]

Phil your videos are always excellent. Great work!

[@PhilsLab]

Thank you very much, Mike!

[@julian7312]

Crazy to see someone reduce a whole year of electronics engineering concepts in a 28 minutes video, you are amazing dude !

[@PhilsLab]

Thanks a lot, Julian - glad you found it helpful :)

[@jrfoliveira]

Fantastic lecture!!! Congrats Phil!!

[@PhilsLab]

Thank you, Juliano!

[@deangreenhough1178]

Great work Phil, Thank you. Im looking forward to signing up to future courses with you. You are an excellent source of information and its application. I always highly recommend you to anyone seeking knowledge and a clear explaination.

[@PhilsLab]

Thank you very much, Dean! Also thanks a lot for recommending the videos to others :) Currently quite busy with work and making videos but am still working on the FPGA/advanced hardware design course.

[@ndmath]

Great video!

[@mostafakh5075]

thank you Phil, I really enjoy your videos, u are the best👍👌

[@PhilsLab]

Thanks for watching, Mostafa!

[@YandiBanyu]

Just when I needed it the most, you delivered. Thank you so much!

[@PhilsLab]

Thank you very much for watching!

[@Mr.Leeroy]

Yeah, this video fills in a lot of blind spots in such a short duration. And yet it is not overloaded with theory. That's rare.

[@PhilsLab]

Thank you, Leeroy!

[@mic03311]

One of the best video on the subject! @Phil I hope you will release more courses in the future. You are a great teacher!

[@muratpinar7478]

Amazing video, many thanks for sharing.

[@PhilsLab]

Thank you, Murat!

[@johnstephenson4428]

Great detail and analysis, very good lecture!!

[@codingspace]

I was searching for these and you uploaded, I think you also got idea from veritasium😀

[@PhilsLab]

Glad to hear that :) I actually don't follow Veritasium, but will check it out now that you mention it.

[@rodrigofaria4498]

Way better than a semester worth of uni classes lol. Great job Phill! As usual, your videos are top notch 👌🏼

[@AlejandroGarcia-rk5lc]

Incredible video as always. Clear and practical ✍️

[@PhilsLab]

Thank you, Alejandro!

[@dickesf8525]

You really make great videos!

[@PhilsLab]

Thank you!

[@AndersNielsenAA]

Another good one! Thanks!

[@PhilsLab]

Thanks for watching, Anders!

[@gino.avanzini]

Wow, this is amazing. Is there any books you recommend for studying this topic?

[@francoclsm6251]

Thanks, Phil. This video is very helpful!!! I hope more similar videos about EE knowledge will coming on your channel.😁😁😁

[@PhilsLab]

Thank you, Franco - definitely have more EE content planned :)

[@IONGROZEA]

Great video, thank you. It will be great if you can make a tutorial for TIA and multistage amplification using op-amp.

[@Wtfinc]

Im here because im confused about something I realized in an opamp schematic. It was my understanding that one input could accept a positive or negative input voltage, however when I looked at the schematic it was only npn transistor on both input. Npn transistors wont turn on with a negative voltage. So either there is npn and pnp opamps or im missing a trick

[@kapishpotnuru1883]

Great video Thank you very much

[@haraldh.9354]

thx for this lesson

[@eduardmihailoiu7609]

Hi, do you know anything that deals with the design of an operational amplifier? do you know where I can find the version with a differential nmos pair and not pmos?

[@suncrafterspielt9479]

Nice Video

[@PhilsLab]

Thank you!

[@jose6417]

Clipping is undesirable unless you want a gnarly overdrive sound, haha! Would be an interesting way to make a hard-clipping circuit or a fuzz of some kind. However, with the usual 9V power rails in a guitar pedal, that would be insanely loud. Great video Phil!

[@PhilsLab]

Thank, Jose! Haha yeah would probably sound pretty rough the way it's clipping there but who knows. Definitely wanna make a video on overdrive/distortion in the near future though :)

[@ivolol]

I think it might have been useful, to compare the major ballpark "specs" of the opamp you created to a real-world jellybean part, like ua741 or lm358; to give some context to how much better (or worse?) a bog standard IC can be.

[@greenberet84]

Hello!! Great video! A question: how did you measure the gain of the input stage and the voltage gain stage? Using a very very small input in order to not reach the supply rails in the output?

[@Techn1cian]

excellent!

[@PhilsLab]

Thank you, Nathan!

[@VoltageLP]

Thanks for sharing your knowledge, Phil =) I'm sitting here in Kyiv about 8 miles from the russian positions and soaking it in

[@kanax2424]

Guten Abend, hast du eine Literaturempfehlung für den Schaltungsdesign? Lg

[@seraphin_creates]

Very good video!

[@PhilsLab]

Thank you!

[@chinmoytahbildar3278]

You are damn good.... Want more videos from you😊

[@atle5191]

Make a video about Crossover 3 way active by Opam, please!!!

[@mateoarv]

Why can't teachers teach like this?
