TSP #32 - Tutorial on the Theory, Design and Measurement of Delta-Sigma Analog to Digital Converters

[@Thesignalpath]

*Please note an error in the integrator function which should be (z^-1) / (1 - z^-1). Thank you to the people who spotted the error. This does not however change the behavior of the transfer function of the noise and signal being HP and LP.*

[@w2aew]

Really nice tutorial, Shahriar - I love the progression from theory, to practical, to real-world effects.

[@Thesignalpath]

Thank you!

[@sarvenipek3126]

TheSignalPathBlog I agree with w2aew's assessment. Very nice tutorial!

[@Afrotechmods]

You are mindblowingly smart, an amazing teacher, and an amazing video producer.

[@hgtrad7655]

Best DeltaSigma Modulation explanation in a simplified way. Keep on your excellent work.

[@sohamblaze]

I am a silicon validation engineer and we work extensively with delta sigma ADCs. As validation people, we often tend to test ADCs as black box. Your video was truly worth it. Very lucid content, and a strong hold on fundamentals. Thanks a ton! Keep this up.

[@h0ll0wm9n]

The most-comprehensible treatment of D-S conversion is in this video. Shahriar has made the tutorial succinct and FUN to boot. Thx!

[@nayanendubiswas662]

First Downloaded offline, then subscribed after watching , and now going to analyse in Simulation tool, awesome video..

[@DIYDaveT]

My God. This was such a well done video. No glossing over of any salient detail. If I watch this about 5 more times over the next few weeks I have the distinct feeling that I will fully understand it.This video is everything a person trying to use KZbin as a learning environment could want:- Highly detailed without ratholing.- Information has a flow which builds on prior concepts, like building a pyramid. No jumping around to this or that BUT with the proper amount of references back to prior material pretty much exactly where it is needed in order to clarify the current point.- Both the abstract and the concrete were presented- CLEAR English spoken with a good mic used.I cannot say enough good things about this presentation.THANK YOU for taking the time and obvious thought to share your expertise!!!

[@MrDrchernobyl]

this video is a goldmine of information, most professor cant explain this content so well, in fact in my experience most people are afraid to go into this kind of detail because they dont understand it that well themselves

[@PriyankaAgrawalrocks]

This tutorial is just wow. Hats off to Shahriar to talk about complex theory of S-D A/D in as simple as words it could be.

[@KX36]

This is one of the best electronics tutorial videos on the internet. You covered a complex subject really well in only an hour. It's a subject which many people know of and make use of, but few bother to understand and those of us without access to higher education and expensive equipment couldn't have really covered ourselves. Great as always, I'd love to see more of the same, thanks so much!

[@jiamingcui2374]

I like it that you are always referring to signal-to-quantization noise instead of just calling it SNR

[@huskyzzaa]

Dude, you're one hell of a beast! This is the best presentation I've seen in a really long time! Thank you so much!

[@peejay1981]

I agree! Brilliant!

[@jimzweighaft8079]

Excellent tutorial. Showing real signals on the scope really brought it home.

[@OrbiterElectronics]

With people like you looking after IC design etc Shahriar, things are in good hands. Thanks for the great vid.

[@StephenHendersonActual]

Wow. Thiis is one of the best videos yet. You apologized for using your tablet, but I think it led to a useful back & forth with your material that wouldn't have been possible with the (fun) single small whiteboard (used in the past). Today, I always knew when you were moving between 'slides' and understood how you were correlating newly introduced ideas on a later slide to fundamental ideas that you jumped back to. Please, please keep up the great work.

[@omgkingdano]

from an electronic engineer here, in the development business for 8 years....awesome video

[@MahdiMohammadi0]

My master's thesis is going to be about VCO-based ADCs which are a type of the Delta-Sigma ADCs. Your video really helped me understand the concepts. Your explanation is better than even most professors'! Thank you, Shahriar!

[@Demonmason77]

The best explanation for delta-sigma ADC on the internet! Thank you so much!

[@b.6603]

This is most definetly one of the best videos on youtube. Wish I had seen this while taking my classes on measurement systems!

[@TheStratexplorer]

This is by far the best video on this topic I've found in the internet. Despite having a very little knowledge about the topic I actually understood the discussion quite well. You are an excellent teacher and I hope you keep up the good work.

[@megabytephreak]

The two tones at 56:30 are the upper and lower images of the input signal offset at +/- 2 KHz from the sample rate (and harmonics). The sample rate doesn't come through because of the nulls in the sinc function at the sample rate ( and harmonics).

[@SalamanderDancer]

Yes! f_s - 2 kHz and f_s + 2 kHz. Aliased all the way up to infinity

[@vinaybhaskarchandratre7762]

Thanks

[@imscuba]

Alot of this was a bit beyond my level, however, as with all your videos, I ALWAYS learn something.. again.. another A+ video. Well done & thank you.

[@davidjereb]

Thank you for producing these videos, Shahriar. You have a gift for making even the most complex stuff seem simple. On a side note, you don't need to apologize for having a bunch of theory in your video. It's an essential part of the explanation and a video without it would be meaningless.

[@321reh]

Your shop Is Nothing short of INCREDIBLE!!!

[@duanebarry2817]

Fantastic demonstration! I really learned a lot about delta-sigma modulation. Designing the digital filter is the next step I would like to take.

[@biteshtiwari]

It is more clearer to me now with output confirming the theory behind this.I am thankful to you for this informative video.

[@lorinczhuff688]

This is my first youtube comment ever. I am a huge fan of the signal path blog. Even though this video is from 2014 I felt that it was important to weigh in because our host requested it. I LOVE the mixture of math, theory and hands on on this site. I don't mind the video length at all. This time is appropriate for the level of detail and care put into explaining the topics. I learn so much on the signal path. Please don't change anything. You are making me a better engineer. You are the mentor who I did not have when I got my first couple EE jobs. Thank You.

[@KarthikeyanKrishnamourthy]

Amazing man. I am a graduate student in Electronics, learning lots of design. I must admit that this video has taught me more than what I would learn in an ordinary class room :) Good job :)

[@jimzweighaft8079]

Excellent tutorial. I especially appreciated seeing actual operation on a scope.

[@TechTins_Projects]

Best video you have done to date. The tablet works very well. I think its a much better way to present this type of technical info. Very impressive!

[@ronaldkoo4574]

Great tutorial! I liked the fact that it concentrated more on the intuition of how delta-sigma ADCs worked and then linked the intuition with actual physical measurements. Bravo!

[@armenforget5980]

Thanks for the great tutorial Shah! In a few key statements, you made some concepts click in my mind that haven't clicked during my many years of study in EE. I hope you keep educating the world for many more years!

[@simonhooper9464]

Great video. Really helpful. Showing the averaging and noise shaping on the scope is a great way of bringing the theory to life. Fantastic job - keep up the good work! A big thank you for taking the time to share your insight.

[@BenjaminMaggi]

I really enjoyed this video, going from theory to practice in just an hour makes an excellent balance !

[@jpopwell1]

very very good. very nice to see the teaching and application, as well as the use of the test gear to show it all.... very very nicely done jim

[@0PAIx]

Many thanks Shahriar, I appreciate all your videos. Well above my level of understanding end to end but I gain many insights which reinforce what I do know, what I thought was well beyond me and the breadboarding of circuits give a good understanding of the workings at the component level. Good to see you back making videos. I appreciate that a significant amount of time and planning goes into every video. My preferences, not so much rip downs, but the theory and circuits with the frequency and time domain images. I look forward to every one and try to get fellow radio amateurs to view and suck up the good theory presented so convincingly.

[@trickyrat483]

Great video. Nothing else matches this depth on KZbin. Well done and thanks.

[@thromboid]

Fantastic - covered everything I was looking for and more! I'm coming at this from an audio perspective - I knew about noise-shaping but didn't realise it was intrinsic to the delta-sigma modulator. Your video will be a great help for my retro-computing project of building an audio ADC for my old Amiga. :)

[@gnalibagatnortkelegn7561]

Really great tutorial! KZbin needs more of these. You are able to glide through a complex topic from theory to actual experiments in a very interesting to watch fashion. Thanks a lot for sharing your knowledge. The experiments are really well thought of. Awesome!

[@johng4609]

Outstanding! Accessible at many levels of understanding, presented extremely clearly. Thanks!

[@williamdillon2715]

Fantastic video as usual! I little over my head with the technical stuff, but you described the broad concepts very well.

[@arcadianelectronics]

Very nice tutorial Shahriar. I really appreciate how you take the time to cover the theory and math behind this class of data converter.

[@mskh744]

Awesome flow of illustration going on here,,Theory and hands-on experience here are priceless..Best way I figured out finally how delta-sigma works Keep up the good work

[@rohitk8690]

I agree too.

[@rohitk8690]

I agree too.

[@moshet842]

This is just amazing! Your teaching style is by far the best I have ever experienced.

[@AndrewMiller_andros]

This was a really great tutorial, and what I have come to love about The Signal Path. More this please!

[@caioalonso7115]

Keep up with such good work and even more people you became your fans! Thanks a lot for the tutorial Shahriar

[@wilvanlierop]

A very nice explanation of a sigma delta adc. A primer for me, to fully grasp the concept in its technical details. Thank you very much for a naother great video.

[@VinodKumar-ho5uw]

Very Nice video to understand and visualize the Sigma-Delta ADC....

[@topherteardowns4679]

watched it all. you are a god amongst men, and your actions are commendable

[@DaruoshAghajaney]

Man, you're an awesome teacher and the amount of knowledge in your videos are amazing.

[@rwarmstr]

Excellent video, as always! The progression from theory to practical application really ties things together. So many university courses are entirely focused on the theory and it can be difficult to fully grasp the implications without practical application.

[@Microelectronicos]

Excellent video-tutorial Shahriar! Thank you very much for all the time you invested in the preparation of both the theory explanation and the lab part in order to demonstrate how the theory is applied in real circuits and everything matches perfectly. Kind regards,

[@babak76j]

zaheran doroste k..... Honar nazd iranian ast o bas..... damet garm, aali bud!

[@rautonkar1986]

Amazing video. Very clear explanation. Loved the part where you demonstrate it with practical equipment to match the theory. Hats off!

[@JackZimmermann]

I love your videos Especially the reviews and repair videos. I learn something new every time.

[@kungfumaster8171]

Your video are first class. Excellent work. Much appreciated.

[@PressPlayism]

Man I really like your tutorial videos Thumbs up! Delta-Sigma was one part I skipped in the exams due to time constraints because it was a really big chapter. But I wanted to understand them sometime and you just helped me with that extremely. Very much appreciated keep the good work up!

[@rcleveacp]

Very good video, as always. A great review of transfer functions, from my collage days. Great explanations. I would like to say thank you for the great instruction.

[@laneboysrc]

Thank you so much for the effort in this video. I never thought much about the inner workings of those compoents. The amout of theory was excellent to give me an understanding, and as a practicioner your breadboard example was fantastic to show it in real life. I wish school was as enaging as your videos back 30 years ago :)

[@rajmathis]

I like your approach. It makes things so simple to understand.

[@kissingfrogs]

As always very much enjoyed your tutorial. Thanks Shahriar.

[@joaorrpinto]

Thank you for the excellent video. It helped me a lot in Digital Signal Processing lectures! Thank you very much!

[@95Davich]

Wow. More videos like this in specific topics of RF plz!. Also, would be great if you can provide some resources for self-learners like books or something that was helpful for you . Thank you

[@RupertHandford]

Fantastic video as always. Love the mix of theory and practical. Can't wait for the next one.

[@rupertrooksby]

45:31 if you want to see a magic trick. Another hugely enjoyable, interesting and educational video Shahriar. Thanks.

[@igsaturation]

Wonderful overall work, wonderful presentation, and wow, what a great lab.

[@porksandbean]

love the way the theory is visualized practically

[@brianku6672]

Great presentation for introduction of sigma delta ADC design.

[@jyothii7312]

Great video... especially the choice of +/-VDD for supply helped me in visualizing it better, the output as pulse density modulated (PDM)

[@flaviaduna]

How can someone not like this? Great, thanks.

[@rohitk8690]

Excellent explanation and demonstration. Keep it up.

[@pangmeister]

I like how rappers stack bills in their video and EE stack oscilloscope, signal generators in the background.

[@mopar3502001]

Excellent video! I really appreciate all the work you do here! Keep up the good work!

[@ehcsaw]

Thanks for the tutorial along with the lab measurement to help solidify the theory.

[@godfreypoon5148]

I am an Electronics Engineer in the time domain, but in the s-Domain I am a Hairdresser.

[@gregdee9085]

Hahahahahaha.... man that's hilarious!

[@knunne1]

Great tutorial but I plan on watching it again to get the other half of what I missed. Great information!

[@gerrysweeney]

I second Alans ***** comments, excellent tutorial on the inner workings of the delta-sigma ADC - thanks for posting. Gerry

[@vukhetamaluleke4150]

Thank you for simplifying this concept. I just have the following questions: 1) How would you sample a square wave? Would the concept still be the same? 2) How can the integrator be implemented using a microcontroller?

[@catalinlazar2666]

Very interesting and insightful presentation. Thank you

[@Tjousk]

I most certainly learned from this. Keep up the good work.

[@yaghiyahbrenner8902]

Analogue Devices will probably make you head engineer in future. Thanks dude.

[@madhirasriharsha]

Nice tutorial, now I am planning to check the DAC video.

[@Parirash123]

It's very good... Thank you very much for sharing your knowledge.

[@rigorouselectronics8089]

Great video. This will help during my MSEE.

[@Proud2bmodest]

Very clear explanation and demonstration, thanks.

[@simonlund4794]

Very nice and detailed tutorial! A very good supplement to my books reading. I especially liked the practical part, as i now know how to both build the circuit and measure it correctly. Now i'm looking forward to implement the Sigma-Delta modulator in the Class D amplifier, that i'm building and measuring it afterwards.

[@reemalsharefi9425]

شكرا جزيلا على الشرح الجميل المبسط حفظك الله من كل مكروه

[@Pierreaudio]

Very interesting topic and perfect presentation! Thank you one more time!

[@Adgjmptw12able]

Great video. Just one thing I want to point out: for a 2KHz input signal, the nyquist sampling rate is 4KHz. If the sampling rate is 256KHz, then the oversampling ratio should be 64 not 128.

[@tehwalris]

Great video. It makes it very easy to understand the most important points, even if the finer details are two complicated for me right now. A video on PLLs would be quite interesting.

[@lironlisha1381]

Crystal clear explanation. Very helpful!!!

[@strekdim2263]

Great tutorial, from theory to practice

[@krish2nasa]

Pretty cool explanation. Thanks a lot Shahriar.

[@spkumar1]

Superb video!! Thanks for sharing.

[@godissogoodtome]

Very well done, such a great video! Watched to the end. :)

[@ThatOhh]

Nice topic, looking forward to watch it! Thanks :)

[@First2ner]

great video as always, nice to see theory and example

[@VladAdamenko]

Awesome video! " I hope you're still there" - priceless.

[@Redline-99]

very cool and interesting, especially the wave form visuals of the bit train
