Is there any difference between CMOS and MOSFET?

difference between cmos and mosfet

Any good links or explanations about CMOS and MOSFET?

difference between mosfet and cmos

MOSFET is a transistor technology. It is an extention of the field-effect transistor (FET).

As with bipolar transistor, where you have NPN and PNP, you can have two kind of FET (P-channel and N-channel).

When creating integrated circuits, using mainly P-channel MOSFET transistors, the device is called 'PMOS'. Similarely, when using mainly N-channel MOSFET, the device is called 'NMOS'.

CMOS are the most common devices, which use an equal mix of P-channel and N-channel MOS, and stand for 'complementary MOS'.

Above, the term 'MOS' is in face a short for 'MOSFET'.

So, MOSFET is a transistor technology, while CMOS is simply a way of designing chips.

MOS stand for 'metal-oxide-silicon'. The MOSFET differt from the plain 'FET' in the fact that the gate is isolated from the source-drain channel by a oxide-silicon (glass) layer, thus, being electrically isolated.
The adventages:
- This is one the main reason why MOS transistors use very little current.
The disadvantages:
- To work efficiently, the oxide layer have to be very small. So small that it can only resist to a difference of voltage of about 30V. It is not an issue since most devices operates on 5V or less, but this is why the MOSFET transistors are very sensitive to static discharges (a simple static discharge are usually in the order of hundred to thousunds of volts). While those static discharges are certenly not fatal for a human, it can well be for a MOS!

cmos vs mosfet

Big Boy, that was a fantastic explaination.

Reference material on MOSFET and CMOS and how they are related can be found at:

cmos mosfet

See the simplest explation is that MOSFET is a single transistor device available in 4 flavours:
NMOS - Depletion and Enhancement
PMOS - ------------ditto---------------

So see 2 X 2 = 4

So ccts built using MOSFETS will have say n devices...but now for CMOS: 1 MOS will be replaced with 2 MOS's(P + N) so see 2n devices (see the word complementary does this trick)

So CMOS is BAD dont use it it will burn a hole in your POCKET....
Hey STOP but you did nt ask abt advantages...
CMOS has so many advantages that the small factor of area usage is simply eliminated... its got speed, low power dissipation (static), that is good...this is for Simple CMOS then you can move on to the more complex CMOS devices...thats a different story for some other day...

difference between cmos and fet

cmos is sheep tecnology and has high integration density making it sheep.
you had say depletion, this is not too much used cause it needs an aditional, and expensive, layer increasing costs

difference between mos and mosdet

I have not worked much with FETS. Don't they require a fairly large VGS to operate. This would be different than the .7volts that a transistor would use. This in itself makes the device sort of design dependent.

mosfet cmos

Just look at a CMOS book like:
CMOS Integrated Circuits by Gray & Mayer

is mosfet cmos

Mos and Cmos here.

differentiate between mosfet,cmos

Cmos is basically a MOS, but with both types P and N channel constructed on a single substrate.

what is the diference between cmos and mosfet

Hi,
this is good about cmos

diff between cmos and mosfet

oh yea........ there is........... a big difference between cmos and mosfet......
why dont u go though www.malvino.com or sedrea and smith book or book by jacob millman u would get a clear concept.....

MOSFET is a four terminal transistor having source,drain,gate and substrate like a BJT transistor (which is 3 terminal ECB).There are 2 types of MOSFETS- nMOS and pMOS.
CMOS is the style of designing digital circuits where we use pMOS and nMOS jointly to design any circuit. It uses n no. of nMOS at bottom called as n network connected to gnd and complimentry network of n no. of pMOS MOSFETS at top connected to VDD.Example An inverter consist of 1 nMOS in series with one pMOS with gates tied together and ivento vin.
