What is a CMOS? [NMOS, PMOS]

In this video I am going to talk about how a CMOS is formed.

[@DKwonShin]

Two of your videos, just 15 min resolved all my confusion from the professor that he went over for 3-4hrs of boring lecture. Thanks man. Life saver.

[@copperwater8456]

these professors that can't explain shit should get fired. no excuse for bad teachers when we have to pay so much money to "learn" (teach our self)

[@hipis200cc2]

thx

[@aonoymousandy7467]

professors are fucking boring, almost half the class was sleeping and the other half was on their phones

Thank you so so so much for explaining this so clearly! You neatly surmised everything that's in my course about CMOS so this is the only resource I have to refer to pass my class! Thanks again! :)

Dude I studied electronics long back and now refreshing my basics. Great video. Thanks.

[@anveri867]

15 min is all it took my teacher drilled my head for 1 hour and still nothing went into my head. Thank you 😊

OMG ! u saved me , I have been looking for this so long ! THANK YOU SO MUCH

[@darthvader5300]

In the early 1980s CMOS being explained in this way is different to what we personally got from a Japanese engineer who said "basically CMOS is more like a layering process but you must first determine what you need so that you will know exactly what is needed to be done first" It is like creating a multi-layered cake. That is the problem with education today, they try to make things unnecessarily complicated and sophisticated when they can make their explanation so simple WITHOUT LOSING THE GIST OF THE ENTIRE SUBJECT itself. This is why Japanese education is far more effective to the point that they made CMOS technology so simple that it allowed them to use simple designs, larger size components, and compensate by using larger size silicon chips the size of small average letters. They did that in the early 1980s which is why they have beaten the U.S IC chip makers in the international market competition. Now with maskless ion beam lithography and electron beam lithography and hybrid ion beam-electron beam lithography using laser guided guidance systems for positioning and alignment, they have made CMOS far effective in cost effectiveness and achive zero defects/zeo rejects status.

[@rabeyaallah]

I think we need a CMOS instead of the pmos or nmos alone because the pmos gives strong high but weak zero, and the nmos gives a weak one/high and strong low/zero. that is why the pmos is stuck to Vdd and nmos is stuck to GND. So we can have rail to rail switching(strong zero and strong one or high).

[@bickyou4696]

sir, what is the meaning of "strong" zero or one ?

[@stego4LP]

@@bickyou4696 It means that it is a clean signal. If you define your high as 1 volt it is "strong" in the sense that the whole 1 volt is transmitted and not only 0,7 volt.

[@rax6254]

@@bickyou4696 PMOS is better at pulling VDD to output and bad at pulling GND to output and NMOS is better at pulling GND to output and bad at pulling VDD to output.

i really appreciate the way u explained everything.... in a very simple manner.... that's a helpful vedio.. i like that

[@StevenStGelais]

Thank you good sir

[@vladomalekovic6368]

we use CMOS tipe because the power drain is much lower on combined tipe than in a pmos on its own ... example in a microprocesor with olnie pmos transistors your power drain of the procesor will be >"100W" but in combined tipe of CMOS you dont need that power. so the CMOS transistor tipe is used in low energy consumption devices or microprocesors (CPU-s).

[@andrewdewar8159]

You've put Complimentary, and,, not meaning to find fault, but its Complementary which means things that are different but enhance each other. I think that's why its called Complementary Metal Oxide Semiconductor, the nmoas and pmos work well together. Whereas , complimentary means giving praise, or something given free of charge. But I enjoyed your video it was really good !

PMOS was also acting as an inverter on its own then what is the advantage of CMOS?

[@TrionityIr]

4:15 Shouldn't Vdd be Vss instead at the top, since it's a P-Mos? It doesn't really matter I think but I wanted to know what you thought about my question.

[@wahidhamidy6886]

[@MdMehediHasan---ss8ih]

Good

[@canadianscholar]

Why do you need a CMOS, if PMOS does the exact same inversion?

[@ElectricVideos]

The PMOS is just a switch. You need values for the transistor and that is why we have a VDD and a ground. VDD represents a value of lets say in binary "1", and for the ground it represents a value in binary "0". Let's say you input it zero, the PMOS is switched on and the VDD passes through the output. The ground does not pass because the passage way is open since the NMOS is switched off given the same input. That is why you need a NMOS and PMOS together to make an inverter, which is essentially a CMOS

[@daemon7777]

You can build every circuit by just using NMOS. This is not the reason why we use CMOS.

[@user-gf3ez5te3y]

Unfortunately ,pMOS and nMOS they are not perfect switches in the real world(there are some delay), In particular, nMOS transistor pass 0's well, but not for 1, pMOS transistor just in the opposite reason. my English is poor, i am not a native speaker. i hope it can help you :)

[@anthonykraimaty]

And we can build every circuit with PMOS. We use CMOS in order to avoid the losses caused by PMOS OR NMOS. We have more than 0.7V loss per gate. When we have multiple gates cascaded this loss will increase in a purely PMOS circuit (or purely NMOS). CMOS is used to minimize the losses. This is why it is used in logic circuits.

[@larryp7687]

PMOS alone would not provide a path to ground. A logical circuit has much more capabilities if another segment within a larger circuit can logically flow to its ground through the NMOS, if logically appropriate, otherwise the logic is stopped, as the positive voltage from the other part of the overall logic circuit has no way to get to ground.

[@iiirannn1]

not clear, what do you mean by output? output at the drain or at source?

[@neerigattisomasekhar4910]

nice explanation sir

[@ElectricVideos]

Neerigatti Somasekhar thanks

[@thomasthereal4067]

6:10 the moment when you finally understand a thing you've had trouble ofer the last couple of months understanding... THANK YOU SO SO MUCH

[@whenyoudiporeosinmilktheyb8329]

great explanation! but why do we need a pmos and a nmos to build a inverter, even though a pmos alone kan invert a signal?

[@abheetl9743]

If there was one PMOS only, you could either give it a low signal, which would short the drain and source, yielding a high output. If you give it a high signal, the drain and source would not be in contact, hence the output would be floating and not grounded as in the CMOS inverter. Correct me if Im wrong.

[@dattatrayphatnaik4735]

in NMOS transistor what should be the value of Gate input for whcih the transistor is in conducting state, will it be high or low or none?

[@user-eq8in2xw6y]

Probably a dumb question but the input voltage on the cmos is always the same across the pmos and nmos components correct?

[@michaelryan2387]

is there a difference from an nmos and p channel misfit

[@shiraku3885]

What pencil u using.

[@gothien205]

can we use only NMOS to make the inverter? it has the same logic table.

[@Semihszy]

ok but why would you not use only pmos instead of pmos and nmos combined if this cmos inverter works just like a pmos?

[@m101ist]

Shouldn't the two inputs be connected together for a inverter output or not gate.

[@dinagiselabluemel9169]

This video just saved my ass… why can’t professors explain like this 😅
