 What is CMOS? - A Word Definition From the Webopedia Computer Dictionary
CMOS semiconductors use both NMOS (negative polarity) and PMOS (positive polarity) circuits.
Since only one of the circuit types is on at any given time, CMOS chips require less power than chips using just one type of transistor.
Personal computers also contain a small amount of battery-powered CMOS memory to hold the date, time, and system setup parameters.

CMOS sensors are much less expensive to manufacture than CCD sensors.
Implementing a sensor in CMOS yields a low-power sensor.
CMOS cameras are usually less expensive and have great battery life.

  CCD vs. CMOS
Renewed interest in CMOS was based on expectations of lowered power consumption, camera-on-a-chip integration, and lowered fabrication costs from the reuse of mainstream logic and memory device fabrication.
CMOS designers have devoted intense effort to achieving high image quality, while CCD designers have lowered their power requirements and pixel sizes.
CMOS cameras may require fewer components and less power, but they still generally require companion chips to optimize image quality, increasing cost and reducing the advantage they gain from lower power consumption.

  CMOS - Wikipedia, the free encyclopedia
CMOS circuits were invented in 1963 by Frank Wanlass at Fairchild Semiconductor.
CMOS (complementary metal oxide semiconductor) refers to both a particular style of digital circuitry design, and the family of processes used to implement that circuitry on integrated circuits (chips).
The CMOS transistors (devices) are formed by the intersection of the polysilicon and diffusion: N diffusion for the N device; P diffusion for the P device (illustrated in salmon and yellow coloring respectively).

 FAQ about CMOS X-ray Detectors
The active pixel sensor technology used in CMOS detectors allows all the electronic control and amplifier circuitry to be located at each pixel instead of being delicately wired to circuitry at the edge of the detector array.
The EnvisionScan™ panel’s CMOS line array detector is shielded from radiation by a thick layer of lead and/or tungsten.
CMOS detectors eliminate this problem because each pixel is amplified separately at each pixel and as a result their signals do not affect signals from adjoining pixels.

 CMOS Logic
CMOS logic is a newer technology, based on the use of complementary MOS transistors to perform logic functions with almost no current required.
CMOS gates are all based on the fundamental inverter circuit shown to the left.
Note that both transistors are enhancement-mode MOSFETs; one N-channel with its source grounded, and one P-channel with its source connected to +V. Their gates are connected together to form the input, and their drains are connected together to form the output.

 Computer CMOS information
CMOS is an on-board semiconductor chip powered by a CMOS battery inside IBM compatible computers that stores information such as the system time and system settings for your computer.
A CMOS is similar to the Apple Macintosh computer's PRAM.
Life time of a CMOS battery - The standard lifetime of a CMOS battery is around 10 Years; however, this amount of time can change depending on the use and environment that the computer resides.

 Axis Communications - Image sensors: CCD vs. CMOS
CCD sensors are produced using a technology developed specifically for the camera industry, while CMOS sensors are based on standard technology already extensively used in memory chips, inside PCs for example.
Recent advances in CMOS sensors bring them closer to their CCD counterparts in terms of image quality.
CMOS sensors provide a lower total cost for the cameras since they contain all the logics needed to build cameras around them.

 Collaterized Mortgage Obligations (CMOs)   (Site not responding. Last check: )
Collateralized mortgage obligations (CMOs), a type of mortgage-backed security, are bonds that represent claims to specific cash flows from large pools of home mortgages.
The streams of principal and interest payments on the mortgages are distributed to the different classes of CMO interests, known as tranches, according to a complicated deal structure.
CMOs are often highly sensitive to changes in interest rates and any resulting change in the rate at which homeowners sell their properties, refinance, or otherwise pre-pay their loans.

 FAQ - CMOS and CMOS Batteries
The CMOS memory is used to store system configuration information, such as disk drive parameters, memory configuration, and the date-time, some of which you enter in the CMOS Setup program,.
The CMOS memory is usually located with the real-time clock in the motherboard chipset or in a separate real-time clock chip.
For example, the CMOS memory is located in the VT82C596B Southbridge chip in the VIA MVP3C chipset on the Epox MVP3G2 Super7 Motherboard and in the AMD-756 Southbridge in the AMD-750 chipset on the MSI MS-6167 Athlon motherboard.

 CMOS
CMOS is a memory resident, Master Boot Record (MBR)/Boot Sector infector.
CMOS is a destructive virus, as it erases the system's CMOS or Setup information about once in every 60 bootups.
When the CMOS virus is memory resident, total system and available free memory decreases by approximately 1,024 bytes.

 What is CMOS? - a definition from Whatis.com - see also: complementary metal-oxide semiconductor
CMOS (complementary metal-oxide semiconductor) is the semiconductor technology used in the transistors that are manufactured into most of today's computer microchips.
Areas of these materials that are "doped" by adding impurities become full-scale conductors of either extra electrons with a negative charge (N-type transistors) or of positive charge carriers (P-type transistors).
In CMOS technology, both kinds of transistors are used in a complementary way to form a current gate that forms an effective means of electrical control.

 TechExams.Net - A+ Core TechNote: BIOS, CMOS, POST
CMOS settings can be changed in the CMOS Setup, which can mostly be entered by pressing the DEL or F2 key during startup (depends on manufacturer, other key or key combinations might apply).
In the CMOS you are able to configure a parallel port to use EPP or ECP.
Another common CMOS setting related to hard drives is Boot Sector Virus protection Enabled/Disabled, enabling this will make the BIOS issue a warning message/beep if a write to the boot sector or partition table of a hard disk is attempted.

 Selecting the Right CMOS Analog Switch - Maxim/Dallas
CMOS analog switches are easy to use, so most designers take them for granted.
These amplifiers level-shift the digital input signal as required, according to whether the signal is CMOS- or TTL-logic-compatible and whether the analog supply voltage is single or dual.
for a typical CMOS analog switch causes a linear reduction of signal voltage that is proportional to current passing through the switch.

 An illustrated Guide to Motherboards
In PC’s there is a small amount of memory in a special CMOS RAM chip.
CMOS data only need to be updated, when different or additional hardware components are installed.
We can conclude, that CMOS data are essential system data, which are vital for operation of the PC.

 CMOS technology demonstration
The previous discussion of the CMOS inverter shows why CMOS logic has (almost) no static power dissipation: If the gate voltage is either '1' or '0' there is no conducting path from VCC to GND, and there is no static current through the inverter.
As in all static CMOS gates, each input is connected to the gates of a pair of N-type and P-type transistor.
Therefore, NAND gates for actual CMOS cell libraries are usually limited to 4-inputs (4 N-type transistors in series) and NOR gates to 3-inputs (3 P-type transistors in series).
