Hello everyone, in this lesson we will talk about what is a MOS tube

2

00:00:05,533 --> 00:00:09,200

MOS tube is also called insulated gate field effect tube

3

00:00:10,000 --> 00:00:13,966

It is a component very similar to a triode

4

00:00:15,066 --> 00:00:19,866

It is only used as a switch in the circuit

5

00:00:21,300 --> 00:00:25,566

But it has a large number of applications in the circuit

6

00:00:27,366 --> 00:00:30,900

At the same time, the MOS tube also has three poles,

7

00:00:31,566 --> 00:00:36,166

which are D pole, G pole and S pole.

8

00:00:36,600 --> 00:00:43,966

Corresponding to the C pole, B pole and E pole of the triode respectively

9

00:00:46,566 --> 00:00:50,133

At the same time, the MOS tube also has a control pole, which is the G pole,

10

00:00:50,166 --> 00:00:55,200

which corresponds to the B pole of the triode.

11

00:00:55,900 --> 00:00:59,133

It can be seen that their positions are also corresponding

12

00:01:00,600 --> 00:01:03,900

Since both MOS tubes and triodes are used as switches in the circuit,

13

00:01:03,900 --> 00:01:15,133

why are MOS tubes used in large quantities in the circuit, while triodes are used very little?

14

00:01:15,566 --> 00:01:16,466

That's because the control pole of the MOS tube does not require current,

15

00:01:16,700 --> 00:01:23,533

that is, the G pole does not require current

16

00:01:23,800 --> 00:01:26,300

It just needs to have voltage

17

00:01:27,200 --> 00:01:30,333

This is more convenient when designing the circuit

18

00:01:30,966 --> 00:01:33,100

The second point is that MOS tubes are less affected by the environment,

19

00:01:33,200 --> 00:01:40,533

and generally speaking, they are more stable than triodes.

20

00:01:41,500 --> 00:01:46,133

Therefore, MOS tubes are widely used in the circuit
