Do you know how transistors work? What is it about transistors that make them the building block of so many electronic items, like computer, laptops, smartphones and tablets these days?

What is a transistor? The transistor is arguably the greatest invention of the last century, or perhaps, one of the greatest of all time. If it wasn’t for transistors, we couldn’t have developed smaller, faster and cheaper computers, telephones, GPS devices, radios, gaming consoles, smart televisions, routers and a device — no larger than a human hand — that integrates all these marvels under the same screen.

This is a short, layman explanation of what is a transistor and how it works.

41 Trả lời “How Transistors Work – A Quick and Basic Explanation

  1. Yet we STILL cannot make a transistor powered guitar amp that is as good as, or better than a vacuum tube powered amp.
    The transistor has changed the world, but I still love tubes, at least for audio, there's nothing better. If you've never smelled warm vacuum tubes, you're missing out.

  2. can someone answer this how can the donors give electrons to the n type semiconductor and make that positive when it has an extra electron that would make it negative. If an atom has an extra electron instead of having the same amount
    protons and electrons it would be become negative

  3. No matter what religion you are you have sinned, you have messed up in life. The Bible says all who sin have fallen short of the glory of God.
         "for all have sinned and fall short of the glory of God,"
    Romans 3:23 ESV
         So in all honesty each and every person deserves to go to hell because we sinned against God. So then it is your own self that sends you to hell not God. God desires that every person be with Him in heaven. Although you might say, or think that if you are a good enough person God will just let you in. But this is flawed reasoning, seeing as how you have sinned against a perfect God, who's standard is perfection. Therefore someone must take your punishment. Thus no matter the amount of work, we are saved through grace and faith alone.
         "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast."
    Ephesians 2:8‭-‬9 ESV
         This grace that the Bible mentions is free for anyone who wants it. All you need to believe is that Jesus Christ was sent by God into human flesh and lived a perfect life and died on the cross for our sins and rose on the third day. No strings attached no work is required to get into heaven although true faith will produce works out of thanks. Jesus Loves you He is alive today. This may be your last chance to accept Him. Please while it is not to late.

  4. The narrator is mistakenly talking about FIELD EFFECT TRANSISTORS (FETs), not BI-JUNCTION TRANSISTORS (BJTs)!

    "Source", "Gate" and "Drain" are the electrode names for FETs; "Emitter", "Base", and "Collector" are the electrodes for BJTs.

    The displayed graphic symbol is, correctly, for BJTs. The graphic symbol for FETs is TOTALLY DIFFERENT, especially for "Metal-Oxide Semiconductor" (MOS) FETs.

    Otherwise, his explanation of "PN Junctions" and their electrical natures is fairly accirate.
