What is CMOS?

Complementary metal-oxide semiconductor is commonly with its abbreviation across the globe i.e. CMOS. This technology is used everywhere in order to prepare those circuits that are known as integrated circuits. The technologies that use this technology of CMOS are static RAM, microcontrollers, some digital logic circuits and microprocessors. There are several circuits that are known as analog circuits in which this technology is commonly used.
These analog circuits include data converters, image sensors and transceivers that are known as highly integrated transceivers. The usage of these highly integrated transceivers is made commonly to construct several types of devices known as communication devices. CMOS was patented by the famous technologist in year 1967 who is known with the name Frank Wanlass and the name of that patent was US patent 3,356,858.

There is another name which is used in translating the abbreviation CMOS i.e. complementary-symmetry metal-oxide semiconductor and in this way the abbreviation should be pronounce as COS-MOS. Complementary-symmetry is actually used because of a fact of using n-type along with p-type metal oxide semiconductor field effect transistors (also known with its abbreviation which is very common in use i.e. MOSFETs) which are also known as symmetrical and complementary pairs, in preparation of CMOS which is constructed in typically digital design.

Low static consumption of power along with the high noise immunity is actually the very significant characteristic of this technology type which is known as CMOS. Most maximum power is used by this technology type (CMOS) when the device is converted from one state to other i.e. from off to on state or from on to off state
