@Mulakulu4 ай бұрын
Correction, there are 4 types of mosfets. You even mentioned them in the video, but for some reason you said there were only 2. Enhancement and depletion just says if they are normally open or normally closed, while n-channel and p-channel tells you if they are activated by a positive or negative voltage compared to the source pin

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.
@dylangergutierrez4 ай бұрын
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_Wideman4 ай бұрын
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.)

I think the constant pressure analogy is more of a BJT thing, where the base must have a constant supply of current to operate the transistor in the "on" state. While a FET is more of a wall switch, it takes power to change states but is relatively efficient when not changing.

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.

Practically there are only enhancement MOSFETs on the market. Depletion MOSFETs are effectively only theory and found only in textbooks. They are nothing you will ever buy. But there are n- and p-channel models. This is missing here. The n-Type has a signifcantly lower resistance than the n-type so you do nearly every trick to avoid the p-channel model.

NPN & PNP refer to bipolar transistors and are current amplifiers, MOSFETs are P channel or N channel and amplify voltage.
