www.bring-knowl... This video explains to you how MOSFETs (metal-oxide-semiconductor field-effect transistor) work and how they are used to amplify and switch electronic signals. This animation describes the enhancement-mode MOSFET.
This is certainly one of the clearest explanations. Most people on youtube gloss right over the significance of the gate electric field and how it enables conduction as an N-channel. And they usually spend too much time describing the depletion layers.
Well in layman terms it's like a faucet, the more the tap is opened (gate), the more water (electricity) flows between the source and the drain (faucet outlet). ;)
Simple and exact explanation. Just perfect! However I was wondering if you would ever do a video on how both BJT and MOSFET can be used as amplifiers. That would be just amazing lol
Thank you for the background music, I am now prepared to fulfill my destiny in a slow-motion battle scene. The transistor stuff was pretty cool as well.
hey thanks man. i suffered very much because i am not able to understand what the structure of mosfet is after seeing this video i got the idea and ur presentation is superb.
Nice video. But it should include when/how a mosfet turns off in my opinion. Also questions, are drain and source swappable? Does a mosfet carry current both ways when on? Thanks.
Hi Thomas, It is a nice video but the explination is te simple to be 100% true. In Razavi book "Fundamentals of Microelectronics" , you will find the real working principle which is realy interesting. With kind Regards, Dlovan
First Of All, Thanks to the Maker/Makers For the Animation. Me Not Being From Electronic Background, have some Question- Why is Electrons Not Flowing From Source To Gate, Why Only Movement is From Source to Drain.? Is it Due to the Fact that Potential Difference of Gate is Equal to PD of Souce? Or Because The Electrons Entering the Gate from Source are Neutralise by the Positive Charge Carriers(Or Something Represented By + Sign) at Gate Terminals? Looking Forward. Thanks Again
Dear Thomas, I am teaching the fundamentals of electronics to graduate students of neuroengineering. Would you care if I used still images of your video in my slides? Of course, due credit would be given.
Two questions: 1) What attracts electrons to move from the gate to the drain 02:58? 2) Isn't it that in reality the moving electrons take the place of the ones in the gate while the ones in the gate are constantly pushed to the right? In 2:58 it is shown as if they were passing on top of them, rather than pushing them sideway.s
But why does the n-type channel (which is more negative?) allow electrons to pass through itself? It would seem that a negative channel would repel electrons with a moderate voltage across source and drain.
Sir. Plz tell me if the positive hole and negative electron combines afterwards what will happen?? Plz Tell me if hole and electron combine together then will it make a space later?? B z here many holes and electrons are combined so that channel is created channel is ntg but space right??!!! Plz tell me sir. Tq fr ur astonishing videos
So a postive voltage on the gate increases the depletion layer between the two n doped sections? Would that make the current between the drain and source reverse bias?
Would it be more accurate to depict the electrons as repelling each other, thereby creating current, rather than providing a sort of "bridge" over which some travel?
