The inverting circle in front of the PMOS can be misleading. If you had an inverting element there, then the whole circuit would be pointless, as you already have an inverter. It should be connected directly, it works already as PMOS drain is connected to high voltage, and NMOS source is connected to ground. If Vin is low => PMOS will conduct, NMOS will block => Out is connected to Vdd (with some voltage drop through the transistor), ie. voltage is high if Vin is high => PMOS will block, NMOS will conduct => Out is connected to Ground, ie. voltage is low This circle might be one way of how PMOS transistors are represented, but I would prefer other ways, e.g. drawing arrows in certain directions at drain/source).
The input voltage to PMOS or NMOS is with respect to source. i.e. Vgs. In an inverter circuit, the source terminal of NMOS is zero (ground), while the source terminal in PMOS is 5 V. When you apply zero volts to inverter, the Vgs for NMOS is Vg-Vs=0-0=0, therefore NMOS is off. Similarly, Vgs for PMOS is Vg-Vs = 0-5 = |-5| = 5 V, PMOS is turned on. For complete explanation please watch ua-cam.com/video/0PUTZU4lD_0/v-deo.html
Then, why don't we just use pmos and nmos inverter, but to combine them together? Seems that cmos, pmos, nmos, all of them give the same output(e.g. High for 0V, Low for 5V).
Bcoz if we use nmos as pull-up then it not gonna charge the output capacitor to Vin or 5 volt but charge upto Vin-Vt or 5-Vt and samiliarly pmos doesn't gonna discharge the capacitor to exact zero volt if used as pull down.
1. Implement an inverter (NOT gate) using CMOS technology by drawing its transistor level schematic and briefly explain its working principles. please solve this
I hope you all can set up a blogspot or something to write an article based on what you have taught in your videos. This is because I really want to cite your reference in my reports. I hardly could find any other tutorials that are teaching this.
You can check out videos from this channel. These videos are meant gor ELECTRONICS and VLSI Aspirants ua-cam.com/video/Xvp4QnV5Qmo/v-deo.htmlsi=xPsRH2Ejb_MLo27y
mam, one question about that when you are given low voltage that time p-mos ON when you are given high voltage condition p-mos OFF WHY? i need clear expleniation???????
Ucanmail Forme you can see a bubble in case of pmos.... That bubble will act as inverter and it'll complement your logic.... When logic is 0 it'll on and when logic is 1 one it'll off.... Just complement
I am also having the same doubt. But i am expecting internal working of mos fet when we apply 0 and 1 instead of satisfying my self by seeing bubble in the symbol....
See...I'll explain it in simple way A pmos transistor gets to ON condition when V gate to source voltage(Vgs) is less than threshold voltage of pmos (Vtp)... practically Vtp is neagtie in magnitude....so when u apply logic 1to gate of pmos Vgs will be positive and greater than Vtp....so transistor goes OFF.....if u apply logic 0 at gate of pmos Vgs will be less than Vtp(negative in magnitude) hence it goes to ON condition.
When VDD and VSS will be interchanged it will act as buffer because when nmos is comnected to vdd and the input is 1, output will be vdd that is 1 and vice versa.

Another good lecture from Ms. Gowthami Swarna on CMOS inverter basics. Thank you !
This was better than a lot of previous videos which I watched , thank you mam
This video is really helpful. The topics are well covered and it has given me a clear concept of the CMOS inverter basics. Thank you.
Explained simple and very well. Thank you.
Your Classes are very useful madam Thankyou
I am telling u this the best video out their ... Proper concept cleared within least amnt of time
Ty maam..ur teaching is very simple and easily understood 😊
Very good explanation method ma'am.. Thank you so much..
Very Useful,,,, Thank you Mam 🙏
Very very nice teaching mam it is easy to understanding
Thank you for always helping us 💝
*#Thanks** a lot mam...in very short video clip...u have shared core concept of this topic....*
Ma'am your explanation was awesome ! Can you make a separate video on IIL and ECL
Very good mam
Excellent tutorial
Well connected
Good explanation in a simple way.
Mam could you please explain the CMOS AND Gate OR gate truth table
Thank you for sooo clear explanation
Thank you for Being here 😊
I really respect you explain very well.
Mam you are a very good teacher..
Outstanding ❤❤
Thank u so much Mam...very clearly explained
Thank you... That's simple and good

Thanku madam..excellent explanation.
simple words but deep learning
Very useful content ..thank you
You are a life saver

Very well explained!
where is the complete playlist, a kindly response would be a great help
can you help me the transfer characteristics(Vgs
against Ids)
Madam what will be the output at different value of input when nmos is pullup and pmos is pull down transistor ??
If you are giving same input to the NMOS ,PMOS,how the one is ON and another is OFF what is the reaction behind this
Pmos has a not gate in it.whatever input you give it you get the opposite
The input voltage to PMOS or NMOS is with respect to source. i.e. Vgs. In an inverter circuit, the source terminal of NMOS is zero (ground), while the source terminal in PMOS is 5 V. When you apply zero volts to inverter, the Vgs for NMOS is Vg-Vs=0-0=0, therefore NMOS is off. Similarly, Vgs for PMOS is Vg-Vs = 0-5 = |-5| = 5 V, PMOS is turned on.

Static power dissipation is very low in case of CMOS inverter compared to discrete NMOS or PMOS
very understandable 👍
You are great all section you are perticepit.
Very good video
But
Symbols of i p mos and n mOs wrong (missing arrow of p mos and nmos)
how is this working efficiently than pmos ans nmos inverter?
Mam plz do a videos basics of VLSI subject
Very very thanks mam😊
Instead writing the truth table while explaining it will be better if you can have a TRUTH TABLE already written and just linked
Why pmos connected pull up network and nmos connected pull down network ??
Bcoz if we use nmos as pull-up then it not gonna charge the output capacitor to Vin or 5 volt but charge upto Vin-Vt or 5-Vt and samiliarly pmos doesn't gonna discharge the capacitor to exact zero volt if used as pull down.
Easier to understand,thanks

Thanks u mam super 👍👍👍👍
How can ECL and CMOS both be the fastest at the same time.... Plz xplain
Madam can you please explain CMOS AND-OR Inverter
if cmos vout max 5v, and i give vin 2.3v how much vout?

beatifull
mam, one question about that
when you are given low voltage that time p-mos ON
when you are given high voltage condition p-mos OFF WHY?

can we use jfets to build a cmos please explain madam
Circuit ❌ sir cute ✅
well explained
super helpful thanks
excellent explanation. thank you
Excellent
Is cmos inverter and cmos not gate same
thank you mam💯🙏🙏🙏🙏
nice inglis
Can u explain when vdd & vss are interchanged
When VDD and VSS will be interchanged it will act as buffer because when nmos is comnected to vdd and the input is 1, output will be vdd that is 1 and vice versa.
