MOSFET Biasing: Depletion Type MOSFET Biasing (Fixed Bias, Self Bias and Voltage Divider Bias)

In this video, the different biasing techniques for the Depletion Type MOSFET is explained.
The following topics are covered in the video:
0:00 Introduction
2:25 Fixed Bias Configuration
5:35 Self Bias Configuration
8:03 Voltage Divider Bias Configuration
11:13 p-channel MOSFET Biasing

Depletion Type MOSFET Biasing:
To use the MOSFET as an amplifier, it needs to bias in the active (also called saturation region for MOSFET) region.
There are three typical biasing techniques for the depletion type of MOSFET.
1) Fixed Bias Configuration
2) Self Bias Configuration
3) Voltage Divider Bias Configuration
In this video, both mathematical and graphical approach for all three methods is discussed and bias stability of each method is also briefly discussed.
This video will be helpful to all the students of science and engineering in understanding the different MOSFET Biasing techniques.

[@nonsuch]

Awesome. These are my favorite type of MOSFETS for audio use. They behave the most like vacuum tubes.

[@whatsnew2807]

I got lot of confusions regarding this topic. All are cleared. Keep it up brother!!! : ) 😇😇😇😇

[@fitwithpratham_sk]

loving it sir

[@mayurshah9131]

Very informative 👍

[@meghanashenoy1100]

Please make video on Opto- isolator. It will be very helpful. THANKS in advance 😊

[@satishpatel8461]

Please make video on dual electrical networks. It will be very helpful

[@azieazhari]

THANKYOUUUU

[@mrigankadas1093]

Please make videos on IGBT...

[@zainaabdin]

Perfect....What about the effect of load impedance on the biasing stability

[@ALLABOUTELECTRONICS]

I am assuming, you are talking about effect of Rd. The load RL, is connected using the decoupling capacitor. So, it will have an impact on the gain. But the resistor Rd will decide the available voltage swing for the amplified output.
I hope it will clear your doubt.

[@omorkhan3437]

why the load line is straight or vertical for fixed biasing where for self and voltage divider biasing the load lines are inclined and going through the origin? if the load lines were straight for self and voltage divider biasing like fixed biasing then variation would be high as fixed biasing.

2:46 sir how Vgg+Vgs=0
Direction is from plus to minus so Vgg will be negative i.e. Vgs-Vgg=0

[@hasanabbas32mirza]

at 7:52 why interchange one mos with another mos for minimum values

[@andreho6902]

So...how to find the capacitor values. I want to simulate this circuit in Multisim but the capacitor values not given. Is there a way to find them???

[@ALLABOUTELECTRONICS]

You mean coupling and bypass capacitor values ?

[@salehakhan8680]

Sir please make this video also in Hindi

[@noorfikhriyahkashfullah9733]

can you put caption? its hard for me to catch up :(

[@ALLABOUTELECTRONICS]

OK.

[@noorfikhriyahkashfullah9733]

@@ALLABOUTELECTRONICS waaa thankk youuu 🥺❤️✨ may god bless youu

[@srishtigupta4982]

Caption in English please

[@ALLABOUTELECTRONICS]

will be updated in a day. please check back by evening.
