Even though it would seem that CMOS circuits require nearly zero power, that is only true when they are not doing anything, i.e. when the clock speed to zero.
When a conductor changes state, such as going from zero volts to five volts, it requires a shift in potential energy. If the conductor has capacitance, that shift requires current. Current times voltage is power. Power times time is energy. Even though the capacitance is very, very small, and the time is very, very short, energy is required to effect the change. Add to that the fact that you want to make this change very, very quickly, and that means you need more current - yes, for a shorter time - but you still need to look at power. Add up the millions and millions of conductors in a high end chip, and you see why they consume a lot of power and why they get hot - especially when you push the clock speeds.

CMOS is an acronym for what?
CMOS stands for Complimentary Metal Oxide Semiconductor. CMOS is a technology for constructing integrated circuits. It is widely used in Microprocessors, Micro Controllers, Static RAM. It is also used in Analog circuits such as image sensors. CMOS was patented in 1967 by Frank Wanlass. CMOS is sometimes referred as COS-MOS i.e complementary-symmetry metal-oxide-semiconductor.
Which of the technology results in least power dissipation?
CMOS
Which logic family has lowest power dissipation?
cmos
What is a typical advantage of CMOS over TTL?
TTL stands for Transistor-Transistor-Logic. N-MOS is a type of a metal oxide semiconductor technology. TTL is faster, but generally uses more power. MOS based devices are slower, they and they use less power. Speed is an issue when dealing with high speed data processing.
Why cmos is used more than other transistor?
Lower power dissipation (except at very very high switching rates, as almost all the power dissipated by CMOS is during switching).
What are the advantages of CMOS memory chips over bipolar memory chips?
Cmos inverter has very less power consumption when it is idle where as nmos inverter still consume power when idle.
What are the differences between bi-cmos and cmos technology?
CMOS circuits utilize complementary MOSFETs, i.e; NMOS and PMOS devices together in various patterns to create functional blocks like AND or OR gates. However the problem with these types of CMOS circuits is that they are inherently low power circuits. They cannot handle large currents. So when your block needs to have a large fan out (need to drive a large no of outputs, i.e; more current required) CMOS circuits fail. That is why we use BiCMOS. They are very similar to CMOS circuits except for the BJT(Bipolar Junction Transistor) output stage. BJTs are capable of carrying large currents, hence BiCMOS circuits are used in cases of large current requirements.
Does CMOS play a major role in modern technology?
Yes, complementary metal oxide semiconductor (CMOS) devices are essential to most modern digital electronic equipment. By making use of both N-channel and P-channel MOSFETs in the same circuit power consumption can be minimized (i.e. only leakage current when idle as one type of MOSFET is always off when the other is on except for very brief periods when changing state) and reasonably fast switching speeds are possible. Most microprocessors and other complicated digital integrated circuits are implemented with CMOS circuitry (except for certain portions where switching speeds faster than can be achieved with CMOS without the power consumption of the CMOS circuits rising too much: e.g. ALUs). CMOS is also used in memory devices that must retain data even when the system is turned off, by using a small inexpensive battery that can power the idle CMOS memory for years without needing to be changed.
What is CMOS technology?
Complementary metal-oxide-semiconductor(CMOS) is a technology for constructing integrated circuits.
Why CMOS is important?
In many devices, the technology is enabled in some of the memory to store the date, time, and other important information. This is due to the very low power consumption of CMOS.
Why do you need a CMOS on motherboard?
You do not need CMOS circuits per se but that's the way many modern components are manufactured. Complementary metal-oxide-semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used inmicroprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for a wide variety of analog circuits such as image sensors, data converters, and highly integrated transceivers for many types of communication.

What are the advantages of PMOS and NMOS?
* reduce the complexity of the circuit* low static power consumption* high noise immunity* high density of logic function on a chipThe most important advantage of CMOS is the very low static power consumption in compare with NMOS technology. On the other hand, CMOS technology is more complex to fabricate then NMOS technology, so it is more expensive. However, almost every todays digital circuits are CMOS. You want to use NMOS only when you want to fabricate fast and low-cost a simple circuit. The most important advantage of CMOS is the very low static power consumption in compare with NMOS technology.
