MOSFET Common Gate Amplifier

/ edmundsj
If you want to see more of these videos, or would like to say thanks for this one, the best way you can do that is by becoming a patron - see the link above :). And a huge thank you to all my existing patrons - you make these videos possible.
MOSFET common-gate amplifier gain, input resistance, and output resistance. This is one of the three core single-transistor amplifier configurations, and critical in understanding modern amplifiers.
Hope you found this video helpful, please post in the comments below anything I can do to improve future videos, or suggestions you have for future videos.

Wonderfully explained. I've 'studied' this amplifier many times over the decades, but this is the most elegant explanation!!

[@manuelfreitas7165]

Thank you sir. I learned more here in 12 min than in my 5 classes about this topic

[@UsamaAhmedZeki]

Thank you VERY VERY VERY MUCH, i relied on memorizing the formulas instead of understanding, Thank you once more

[@keerthi5051]

Thank you soooo much for all the three videos on amplifiers using MOSFET

[@foreverfugazi245]

7:55 Truth always comes out unexpectedly... 😢
Thanks for the content, and the warning

[@Pasta_fries]

Sir thank you so much , my professor just reads through stuff instead of explaining .

[@aaronwilson1086]

I'm brand new to diving into electric power supplying or anything , being spurred from car audio....twenty years later who knew I actually enjoy learning this stuff. And using a soldering iron. Lol

[@armenpirenyan9455]

It was a really useful lesson, thank you)

[@patrickbuchanan2273]

Thank you for taking the time to make this.

[@Harrygolfs]

Thanks for taking the time to make these

[@MohamedHassan-zi7ms]

wow!!
you made me take it easy .. all of thank from egypt

[@huwinner2428]

why cant my professors explain this like you do? They never told me that you could just "test" for the input and output resistance. My textbooks don't even mention it!

[@Bingong556]

Great channel helped me out big time already

[@GorgeTony-y5p]

I'm wondering what the six hidden videos're. WONDERING...... ;)

[@fatmacn724]

Thank u sir. From Türkiye!!

[@Steve-GM0HUU]

Very nice explanation, thank you.

[@MohamedFazal]

Wow. You just made this a lot simpler.. thanks..

[@jasonlau6959]

Thank you , really learned alot from this video

[@abdxlive]

Explained Well 💚

[@adityaaman3231]

Very nice explanation 😁

[@bbhh-ud9zo]

thank you so much

[@박기태-r6u]

you save my life

[@harikaharika6842]

U helped alot sir thank you sooooo much🤩🤩

[@oguz8153]

Thank you sir.

[@yusufklc1184]

excellent

[@nahsam]

This is great

[@aratishah3691]

Can you please do it with gmb

[@aishikdas]

Just a confusion will not the drain or the output be grounded as if not then Itest will not be equal to gmvgs but will be kcled with Rd.

[@user-mj3ef]

How can we see the list of all videos? Is there any video on biasing? If we become member through patreon are there other videos? But if so I would like to ser the topics before I do that. Is it possible?

[@shreyanarayan1333]

Thanks for the video! Can you explain how the analysis would change for a PMOS vs. an NMOS?

[@JordanEdmundsEECS]

In a PMOS, you basically swap Vgs for Vsg and you swap the direction of the current. It ends up being very similar, so it usually gets short shrift.

[@AvadaKedavra943]

What if Vin is supplied with a voltage source Vsig with source internal resistance Rsig? How does Rsig affect the analysis?

[@JordanEdmundsEECS]

Great question. You'll have a resistive divider between the source and the amplifier. If you know the amplifier's input resistance (this is something you can calculate), then it's as if the voltage is just smaller by the factor of the voltage divider. Everything else is the same.
