The FET (field effect transistor)

This is the first of four movies (see below) The Field Effect Transistor made its entrance into industry in the shape of the JFET. Some time later, its younger cousin, the MOSFET, made a splash that continues to make it the centerpiece of digital electronic systems this day. I find it "natural" to explain the evolution from the JFET to the MOSFET using the simpler JFET mechanisms first. That is the approach: we begin with the JFET and then we move on to the MOSFET (in three aditional movies). I have also included a few tutorials, all listed below. I hope you find them useful.

Whenever I feel down, I come here..not to study..but listen to his voice , he makes us feel like everything's gonna be alright.

[@knartfocker_]

This guy's voice alone is worth a thumbs up.

[@Danielkehinde-dt8td]

I wish professors would come and learn from you how to present their lectures to students. You make everything easy to understand. Thank you very much, Sir.

[@rolinychupetin]

Wow, thank you!

[@coryelizabethbazzle4486]

You, Sir, deserve an Academy award for holding my attention for over 30 minutes on this subject.

[@rolinychupetin]

If I had not lost the capability for blushing, I would be crimson red right now. Thank you for your very generous praise.

[@rolinychupetin]

Just a comment on way of speaking: near the 9:27 point, I describe the source and the drain as the parts of the channel where electrons "appear" into the channel and "disappear" off the channel, correspondingly. Of course, the electrons will not disappear from the circuit, they will just continue their journey through the cables, external resistors if any, and through the source to "re-appear" at the source terminal of the channel again. This way of speaking, which was coined by the original creators of the device may sound odd to modern ears. Remember, the "appearance" and "disappearance" is given with the channel as the proverbial context. I thought this would be evident, but it was not so to one of the almost half a million viewers, so I figured that this comment might be of help.

[@SwineOMGFlu]

Your voice is so smooth I get goosebumps. Definitely kept my attention span for the entire video. Nice job!

[@richardremi]

Wow, I am not going to fail my exam after all.. Thank you for this video.

[@Liviu75tx]

This was a great refresher ! I studied the transistors (and I kind of hated them) in college, almost 20 years ago and I wish the theory was presented then in such a clear and enjoyable way as it is in this video. Thank you for the explanation, and for your willingness to share the knowledge and make it so accesible. Hats off for that. And, I love the accent.

[@chandraprakashpatel9334]

great teachers can make even most boring subjects most interesting...and you are the one. Thank you

[@anindya8887]

your video has just made me amazed... for an hour, I was thinking, how one can teach so smoothly... easily.... like a music... I have shared your video to my students... even teachers can learn from your video...... and what an amazing voice you have.... thank God you are in this "field" ("field of Electronics")

[@razorr1920]

Well explanations everywhere but the fact you feel the need to share and reasons of your belief, hats off sir. You deserve all the gratitude. And that voice, i would say is more of a capturing one, not letting the visitor stray... I would like to send you some of my appreciation as a gift if i ever had your mailing address.

[@rolinychupetin]

+razorr1920 Your kind words are gift enough, many thanks.

[@aditya417]

u are gr8...this is the first time in my life of 32 yrs that i hv understood FETs

[@TheAndykibz]

Not even watched the video yet but from the comments I feel very optimistic. Hope I won't be disappointed

[@rolinychupetin]

Dear Dr. Arias, Thank you so much. It is very kind of your to take the time and post, and you are an inspiration to the rest of us too. Sincerely,

[@pablosanchezmunoz]

Congratulations! This is the best master explanation about transistors components I have ever seen: really accurate, clear and detailed. Thank you!

[@aliaslmx]

I love your warm voice! It's a pleasure to listen your lectures! Thank you very much!

[@davideophile]

your EPIC TRAILER voice can make anything exciting!

[@rolinychupetin]

You are so kind. I really appreciate your comment. Sometimes, I'm a bit self conscious of the sound of my voice, you see, I can't hear, or at least not too well. So, I have just an idea of what my voice sounds like. Thank you very much.

[@davideophile]

Haha. You have nothing to worry about! :) Even if you're having a lecture about the history and chemical composition of a potato, I'd still gladly listen just to hear your epic voice.

[@adampilsniak602]

I would like to thank You! I have a lecture for foreign students (my native language is Polish). Your presentation is very useful because of electronics vocabulary and your pronunciation. Your description of electronics phenomena is glorious and clear! Voice ... of course cool.

[@nhantranb.5172]

I completed my major in mechanical engineering and somehow struggles in dealing electronics stuffs. This kind of educational material could never be better and really help me a lot. Deeply appreciated!

[@rohitkothari3430]

This is an excellent tutorial starting from basics of PN junction and step by step building into understanding of whats going on inside FET and relating it with its I-V characteristics. I love the way the lecture is organized and detailed, it couldn't have been any better. Thank you so much for teaching me and I look forward to your MOSFET video.

[@aakashnegi4653]

THANKYOU SIR FOR THAT NOW I UNDERSTAND HOW FET WORK ALL MY TEACHERS DON'T KNOW THAT AND REFUSE TO TALK ABOUT IT

[@yemiobisesan6333]

This video was truly inspiring!!! I understood almost everything even though it introduced an entirely new transistor I knew hardly anything about before. The diode tutorial bit was well worth it as well.

[@Candyman97]

It has probably been thirty years, since the last time I have seen any equation, and it is hard to believe that some of what I learned in high school stuck. You sir are a great teacher, and you explain it in a way that is easily understood, well done!!!

[@amandafalke7670]

What an incredible job you've done in describing FET transistors. Thank you very much - a great overview. Excellent theory explanations - crystal clear!

[@elderaze]

Respect from India! Loved the tutorial! And the voice of course! Take a bow, sir!

Excellent! I learned in 30 minutes what my teacher said for a month!

[@rolinychupetin]

Thank you Mr. Rodriguez, but I cannot take all the credit. Your teacher did the ground work. He was like one of those Soccer players doing the hard work of getting the ball in the shoot zone. I just did the scoring kick. GOAL!!! Heh, thanks though.

[@rolandorodriguez421]

Yeah, maybe you're right, thanks a lot again. Anyway, I hope find more videos about some topics of the next courses I'll take at University.
