0:24 Construction of Enhancement MOSFET
1:25 Working of Enhancement MOSFET and pinch-off Condition
8:08 Drain or Output Characteristic of Enhancement MOSFET
8:31 Different Regions of Operation (Saturation, Cut-off and Linear Region)

11:03 p-channel Enhancement-Type MOSFET
12:54 Electronic Symbols of n-channel and p-channel Enhancement MOSFET
Enhancement-Type MOSFET?
The enhancement type MOSFET is similar to the Depletion-type MOSFET. It has three terminals (Drain, Gate, and Source)
But there is no conducting path/channel between the drain and the source terminal.
But by applying the control voltage between the gate and the source terminal, the channel is formed between the drain and the source terminal.
The required voltage to form this channel is known as the threshold voltage. And once the channel is formed then by applying the voltage Vds, current can flow through the device.
So, when there is no control voltage, then Enhancement MOSFET remains OFF.
And once the channel if formed then as voltage Vds increases, the current Id also increases.
But at particular voltage Vds (sat), the drain current Id gets saturated.
And it happens when the pinch-off condition occurs.
In the video, the pinch-off condition is explained in detail.
Different Regions of Operation:
The MOSFET can be operated in three regions.
1) Saturation or Active Region
2) Linear or Ohmic Region
3) Cut-off Region

@tomc642 5 лет назад

Again, a nice conceptual explanation of a difficult subject. The enhancement type NFET is the most important transistor in IC design. I look at pinchoff as being due to opposing electric fields under the gate at the drain.

Sir may i ask you something, do you prefer to read electronics books by Thomas FLOYD ?

@topquark22 3 года назад

"Source Drain" naming is very confusing. I guess it refers to electron flow, not conventional current flow. I wish they had stuck to conventional current because the arrow is reversed and it's hard to remember whether the source or the drain is the positive or negative terminal.

@AbhijeetKumar-pk8tg 3 года назад

how is the source and substrate reversed biased because source is at same potential to that of substrate

@ALLABOUTELECTRONICS 3 года назад

Yes, true. It will remain unbiased when source and substrate are at the same potential.

@Vaish-es9rk 2 месяца назад

4:25 How are both pn junctions reverse biased sir ? And what is the poalrity of source terminal here ! Because it is connected to ground and also to negative end of battery and substrate is also connected in similar manner !!!! Kindly explain this sir !!!

@nissanbiswas8432 Год назад

Here Enhancement N-type MOSFET Gate biasing connection wrong. Gate voltage will be positive.

@mohammedsohail95 4 года назад

Sir, electrons are attracted towards gate because their is a insulated layer between gate and body.please answer my question

@siddheshpatil5170 4 года назад

Imagine when you take two magnets. One under the table and one above the table. They both would still attract to each other. Thats because of Magnetic field. And here, its because of electromagnetic field.

@bullfinch5715 3 года назад

4:37, How both junctions are reverse biased?

@ALLABOUTELECTRONICS 3 года назад

When Vds is applied, the drain is at a higher potential than the source and substrate. so, that PN junction will be reversed biased. On the source side, since both substrate and source are at the same potential, that PN junction is also reversed biased. I hope it will clear your doubt.

@bullfinch5715 3 года назад

@@ALLABOUTELECTRONICS upper PN junction understood. But lower Junction , both source and substrate are at same potential right.

@ALLABOUTELECTRONICS 3 года назад

Yes, when both are the same potential then it is unbiased. But still, there will be a depletion region at the PN junction. Of course, at the drain side, the depletion region will be wider.

@Vaish-es9rk 2 месяца назад

Sir it's not clear about source side Will a junction be in reverse bias when both p and n are at same potential also ??@@ALLABOUTELECTRONICS

@muhibullah7512 3 года назад

Sir from 12:31 to 12:36 you say that if Vgs is greater then Vt then the mosfet will operate in cutt off region...No Sir if Vgs is less then Vt then it will operate in cutt off region I'm I right sir.........plzzzzz answer

@ALLABOUTELECTRONICS 3 года назад

If you closely observe, I am referring to P-type MOSFET. For, p-type MOSFET, Vgs will be negative. What you are saying is true for N-type MOSFET. I hope it will clear your doubt.

@2goku272 2 года назад

4:30 : Excuse me Sir, why both PN junctions are reverse biased? Thank You

@ALLABOUTELECTRONICS 2 года назад

The lower pn junction will remain unbiased if substrate is at the same potential as source.

What abt the third case when Vds

@BiplaBhatt 4 года назад

This mosfet schematic will not work in real. To have gate control you need to overlap gate electrode with some part of source and drain, and without that there's no gate control so mosfet won't work at all. Please correct!

@abhishekagrawal542 Год назад

Sir in saturation region there is no current is flowing from drain to source then how MOSFET is work as amplifier please explain

@ALLABOUTELECTRONICS Год назад

In saturation, actually the current is almost constant. On top of the biasing, when the small signal is applied to the MOSFET then it is getting amplified. I have already explained that in the separate video. Please check this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-utBRWK4GmmE.html Further, you can check the MOSFET playlist for more information. Please go to the playlist section of the channel, you will get it.
