To be very frank......Today I understood the complete and perfect working of transistor..which I never understood in my entire 4 year of Engineering course.!! 👍 Thanks
bro i have no clue why they dont just show these videos in college its way easier to understand instead of just listening and trying to imagine it in your head
@Boris the Blade I fully agree with you. It's just that these types of videos and the way we can all access this information at the wink of an eye wasn't a thing only a decade ago or so. The educational system is based on thousands of years of gradual improvement and this sudden shift of information gathering takes time to implement at an acceptable level.
Yeah but thing with these type of educational video is that it doesn’t induce creative thinking .if you are always indulged in such computer graphics explanatory video you brain will not be able to produce new imaginary thoughts and will always seek for a explanatory video (which may not be available all the time in every topic) This was main argument used to answer why there is not projector teaching in every school in the countries like US, norway (developed rich country) . It doesn’t encourage creative thoughts in student that is really vital.
Boris the Blade but... what's so complicated here? Dunno, I just read that stuff in a book and had no problem understanding, since words explained what's going on. Americans have strange problems
Students these days are so lucky to have access to these videos. Back then in my 12th class I used to skip these chapters as it was difficult to understand these concepts without proper picturization. Great work Lesics!
I get the fundamentals, but how the task of manufacturing these MOSFET switches to work at a microscopic level is still mind blowing to me. Appreciated the video.
I was a tech in the navy, had to learn this in school there. It was all computer training, there was no teacher but a proctor, just to keep us in line basically. The training breezed over this subject (transistors in general). I wandered the school building looking for a senior ET who knew what they were talking about enough to explain this in detail (like in this video) for so long. I didn't become comfortable with transistor theory until after I graduated and found resources online like this. Stuff like this is invaluable!
You are very good at what you do... Thanks for taking the large amount of time to set up shots as well as editing... vid was so good I had to watch it twice
@@alchemist2048 well, he kind of has a point with the trillions. While their is not trillions of transistors in a single machine. To serve this video would require a server to host this video. a server which no doubt has multiple cpus in it. at 3 billion transistors per cpu we're at about 12 billion. then the content would be requested by the client machine which would then have to request the data over the internet which involves hoping multiple routers and switches. Say on average, it takes 10 hops just to get to the data center from your home. All those routers also have cpus and ram ect with transistors in them. and then the content has to be sent back to the client machine hoping over all those routers again. if its over a TCP connection that requires a 3 way handshake which would require more data packets to be traversed back and forth. and again if you implement a VPN encryption into the mix, thats even more router/server hops. by the time you're done the data could very well have passed over a quarter of a trillion transistors.
@@airsofttrooper08 Agreed , but I assumed he was talking about the processors in his phone/PC/laptop that rendered the video, which is maxed out at billions and not trillions. You've got a point too, if you look it the other way, indeed it got trillions but here I assumed something else.
i must admit that it took me couple of years to grasp concepts of electronics. it is exactly what you would imagine with conventional teaching after few years till you get used to symbols, vocabulary maths and physics of electronics. this visual learning is actually great. simple yet powerful, a person would understand this in no time without spending much time. kinda feel silly to know all this could have been much easier. better late than never, thanks tons. keep up the great work.
You should follow up with a video on CMOS sensors. Also good to see you in the intro. You deserve more credit for these amazing videos and clear explanation.
Dude how tf did you are you the only person on UA-cam who can explain how Mosfets work. Iv been trying to wrap my head around how mosfets are used. Iv spent weeks trying to figure it out. Now, thanks to you i think i finally understand. Great video, keep them coming!
this man has the ability to teach the next Tesla of our generation, when schools teach nothing past simple interests this man teaches the complexities yet so simply and eleqeuntly
I was watching a video by a Power Electronics expert who was trying to explain the operation of a MOSFET. He spent 30 minutes trying to explain but his explanation was disastrous, at best. This 7 minutes video is worth all the effort he was putting.
I liked the intro. It is cool to see the people behind the camera, and their passion for the subject. Keep or lose it either way the videos are of such a consistent and high quality I hope they continue. :D
OMG SUCH A CLEAR EXPLANATION YOU HAVE GIVEN, HAVE SEEN MANY VIDEOS TO UNDERSTAND THE CONCEPT WHICH I IMAGINED WHILE LAERNING, BUT I COULDNT GET THROUGH IT. I WOULD RECOMMEND THIS VIDEO TO ALL ELECTRONICS PPL
This is a great video, but it would have been even better if you discussed the channel pinch-off and saturation. Those are very important concepts for MOSFETs. Part 2, perhaps? Thank you for all that you do!
This is the clearest and best explanation of this confusing topic. Finally, I understood how the hell the MOSFET works. This video is priceless. Thanks a lot.
I watched a video where a lady tried to explain it... couldn’t understand much. Nothing against the ladies, but this video is simply perfect. Even a person with basic electronics knowledge can comprehend it easily. Great job!
This video is excellent. I've been struggling to find a study material which explained the role of dielectric in gate but i couldn't find it in any video. This is perfect and extremely clear, things we would never find in a textbook. Thank you!
Hey Karthik Short answer. Imagine you are burning H2. The reaction is H2+O2=H2O The energy released from this reaction is what we want. If you burn it, a lot of heat is wasted on heating the water vapor, and other materials. So, how does a fuel cell work? Super simplistic version. Imagine you have an electrolyte in shape of a sheet. On the left side, you have H2, and on the right side, you have O2. Hydrogen diffuses inside your electrolyte and becomes Hydrogen ion.H2->2H+ + 2e-(Hydrogen ions and 2 electrons) Hydrogen moves through your electrolyte until it reaches the right side of the sheet. Your electrons move through some wires to the right side. (you use the electrons inside the wire to turn a light on, or any other use of energy) on the right side, your Oxygen molecules attract the electrons and become Oxygen ions. O2 + 4e- => 2O2- Oxygen ion then reacts with Hydrogen ion, and emits water. O2- + 2H+ => H2O So, your overall reaction is the sum of these reactions H2 + O2 => H2O This is the super simplistic version of something like a PEM fuel cell, in which Hydrogen ions are the moving species. Wikipedia and other sources should have more info for you.
OK, Engineering school was about 30 years ago for me. For all of you that think that this is a replacement for what is taught in school you are sadly mistaken. This is a nice introduction. A fun little break to be shown in class, but to put it in old terms this is page one of a 300 page text book. There is a lot more physics behind this that you need to understand. There is a lot more math behind this to create actual working examples. How is the material doped? What type of substrates are used? What is the difference between p channel and n channel. Ect, etc. This is a nice introduction, but now you have to put in the work and the time. I guess I have become that old fogy.
I learned about hole flow in USN Avionics School in 1972. Worked most of my life in electronics from 9 years working on well logging tools and surface equipment in Prudhoe Bay, Ak and then 30 years communications doing everything from phones, microwave (not the kind to heat food🙂) fiber optic and working a gateway earth station. I would work with all types of circuits from low speed analog and 64k to terabyte. I remember the old days when we had to actually do component level troubleshooting and repair. Hell, in the Navy we had both tubes and semiconductors. I wonder if they even teach tubes anywhere anymore.
Disappointed the animation implies that the cross-sectional slice of the MOSFET is used. That cross sectional 2D shape Should be extruded into a very long transistor and folded up for compactness.
first time i watched this video , i felt it is important but couldnt understand fully, But when i was studying the eletronic subject and basics get clear. Then i watched this video again Then i found this video is the Best video ever made and very much helpful and eye opening. Great job Lesics Team. Thank you very much for the great animation

why are those atoms so happy?
Cuz they are doped with drugs
And they get to be in LE’s videos. Atoms say Cheese!
Because they got their Ball's😹
Why living happy is good for health
You'd be positive too if you lost an electron.

this video is just 7 minute 40 seconds but to be honest this is almost 1 week of course . due to animation many things made fast forward.
But Now MOSFET is Replaced by *FINFET*
Wait. What?
I think FINFET is a type of MOSFET.
The inner working of FETs (Field Effect Transistors) is pretty similar in any case. BTW, MOSFET stands for Metal Oxide Semiconductor FET.
Less than 22nm technology uses FINFET , MOSFET's cannot be used due to various problems and one main reason being punchthroughEffeat.
All our latest cellphones have FINFET's not MOSFET's
Superb... 👍👍👍if every topic of physics is coverd like that ....then nothing is impossible to understand.... 🏆
