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

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.

Man your 8 min video clarified hours of lectures given by my professor

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.

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

7 mins solved my 70hrs doubts. Thanks mate.

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! :)

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).

Literally i don't find video related to this topic... man your video help me a lot

Thank you so much, I really understoood it CMOS, NMOS and PMOS. This channel is best!!

But a PMOS alone is also inverting his signals ? why we need a NMOS transistor too, to make a inverter. Why we dont use only a PMOS ?

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 !

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

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

cscholar

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?

Before this I watched a 30 minute video that just gave me an headache. Yours was extremely clear and easy to understand. The only problem was I was unable to click on the box for the practical example, but the video is five years old.

The educational pill i was looking for!!🎉🎉

This video is something else, keep it up buddy, hats off to your explanation

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

apiitg

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

thomasthereal

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).
