It can't pass this MOSFET, so the LED will be off.

它不能通过个 MOSFET，因此 LED 将熄灭。

So the MOSFET doesn't really do what we expect anymore.

所以 MOSFET 不再真正发挥我们的预期。

This is just an N-channel MOSFET to see what these things actually do.

只是一个 N 沟道 MOSFET，看看些东西实际上做了什么。

And a higher current means that we can put more charges into the gate capacitance and thereby turn the MOSFET on faster or discharge it faster and turn it off faster.

更高的电意味着我们可以将更多的电荷放入栅极电容，从而更快 MOSFET 或更快放电并更快关闭它。

Then there is a certain threshold in this MOSFET where it starts to open up and starts to conduct current to turn on the LED.

然后在个 MOSFET 中有一个特定的阈值，它始并始传导电以 LED。

So the setup time, for example, is you need some time to chain, so to charge up all the gates of the MOSFET in such a D flip-flop or wherever else.

因此，例如，设置时间是您需要一些时间来链接，以便为此类 D 触发器或其他任何方的 MOSFET 的所有栅极充电。
