    Yes liked it very much. Did my electrical engineering about 41 years ago. This type of learning experience was not available at that time. My father wanted me to build induction furnace at that time but I didn't venture into it because of lack of clarity. I opted for the clerical job 😭😭😭

    I don't know why people believe bjts are slower than mosfets. Principally bjts are faster than mosfets. Mainly because bjts are current devices and mosfets require charging of the gate capacitance during any transition.

    • @NoSpeechForTheDumb
      @NoSpeechForTheDumb Před rokem +5

      Yes this drives me crazy too. It's because people are stupid and need simple messages. In fact: A MOSFET of the SAME size and overall specs as a BJT ALWAYS switches SLOWER because of the gate capacitance, but MOSFETs are generally much smaller in size, so it's all pointless to compare.

    • @TheWeedOperation
      @TheWeedOperation Před 7 měsíci +3

      @@benyomovod6904 They are fast because the individual mosfets are made to be very small reducing the charge required to turn them on and off. That is one of the reasons why fabrication size reduction are so important in the chip industry. When sizes are matched, bjts tend to be faster than mosfets. The additional reason mosfets are used in cpus is because when they are fully turned on or off they don't need any additional power to stay in that state. This makes for lower power devices.

    It’s ideal to magnify your processors if you can, and calculate the leads from the Cpu core. Core 2 Duo has about 5-10 more leads to the motherboard, then Pentium Dual core (laptop cpus).

    When we include temperature in any electrical device like but and MOSFET, it will start to be "confusing". Like what Physics Law or Principle that relates temperature and resistance? Can't name one law/principle.

    • @absalomdraconis
      @absalomdraconis Před 2 lety +1

      A MOSFET is essentially a combination of a BJT and a JFET. The JFET part is added by putting a layer of insulator on the BJT, and then adding a 4th electrical connection on top of the insulator, placed above the "base" region of the BJT; the insulator will let the BJT base "feel" any electric charge applied to the 4th terminal, but will not allow the electrons to go from the 4th connection to the BJT. With this 4th connection placed, the base is then tied to one of the other BJT connections, chosen so that when the MOSFET is connected normally, the base will be _forced_ off. After this is done, the 4th contact (the "gate" contact on a MOSFET) can then force a small area directly under itself to turn on, but cannot force the entire BJT on.
      Now, to actually answer your question, tying the BJT's base to one of the other connections has a second consequence: if you hook the MOSFET up _backwards,_ then the base and the BJT connection that it is _not_ tied to will form a diode.

      One use of mosfets is controlling power . . . I use it in a custom console of mine to control power flow between battery and charging port. While charge is applied via USB battery does not dissipate power but when USB is removed battery can now discharge to keep console running. This prevents battery discharge when plugged in
