      The way to prevent this is to use a high resistance resistor (usually 10k or close) connected to the gate and source.
      It is called a pull up resistor on a p-channel MOSFET, or a pull down resistor on an N-channel MOSFET.

    MOSFETs are more efficient than other types of transistors and 10 to 60 times faster than them. Also, it can be miniaturized better to put in a chip. But they are also more delicate to electromagnetic pulses and electrostatic discharges. Even so, we made our civilization to work around this delicate technology because there are no better options, they represent now 70% of semiconductor's market.

    • @dylangergutierrez
      @dylangergutierrez Před 3 měsíci

      Incorrect; MOSFETs are not fundamentally faster than other sorts of transistors. Bipolar junction transistors (BJTs) and HEMTs both have higher fundamental frequencies than FETs. You're right about extreme miniaturization though; it's much easier to make a bunch of small MOSFETs than BJTs, and due to their lack of DC gate conduction, they're better for tasks like memory and processing.

    The spring in the water analogy diagram seems worng. If you remove the voltage, the channel will remain open as it's controlled by charge which will stay in the gate until you remove it (eg. by shorting to the source pin)

    • @Graham_Wideman
      @Graham_Wideman Před 2 měsíci

      Incorrect. The signal you apply to the gate is a voltage. The upstream circuit does not apply and remove a voltage. It applies a positive voltage to turn on the Source-Drain path, and applies a different voltage, zero volts, to turn it off. (Assuming an N-Channel enhancement mode MOSFET example.)

    Well yeah, but no. There is nothing like spring to get Mosfet to off state. It is exactly the opposite. If the gate is charged, it will stay open until something will discharge it. And other thing, spring needs force to push it open. But Mosfet's gate does not need current to open, unless very high speed is required.
