CMOS (Complementary Metal-Oxide-Semiconductor)

CMOS 

What is the full form of CMOS?

The full form of CMOS is Complementary Metal-Oxide-Semiconductor. CMOS is an integrated circuit built on a printed circuit board. It is a battery-powered memory chip that effortlessly holds the initialisation data. The BIOS uses this data to turn on the device, i.e., during the bootup process.

  • The complementary word refers to the user charge, that is, either PMOS (positive MOS) or NMOS (negative MOS). CMOS utilises one charge at a time.
  • CMOS consumes less power since charges can remain for a prolonged period of time in one phase and, therefore, only consume energy whenever necessary.
  • Transistors focused on CMOS do not heat up and yield a high speed.

Why Do You Use CMOS?

As stated above, CMOS abbreviation is used to design the Integrated Circuit. This technology is applied in microprocessors, static RAM, digital logic circuits, and microcontrollers. The key features of Complementary Metal Oxide Semiconductor technology are elevated noise immunity and low static power consumption.

Who is the Inventor of CMOS?

In 1963, Frank Wanlass invented CMOS at Fairchild Semiconductor. On the other hand, the CMOS Integrated Circuit was invented in 1968 by Albert Medwin and his group.

How CMOS Works?

The full meaning of CMOS abbreviation is Complementary Metal Oxide Semiconductor. This is a kind of technology that is used to reserve the start-up data and to plan the Integrated Circuit board. It is called complementary as CMOS carries both the PMOS and NMOS. Complementary Metal Oxide Semiconductor provides BIOS with primary data during booting.

Applications of CMOS

  • Microcontrollers
  • Static RAM
  • Microprocessor
  • Digital logic circuits
  • Image sensor

What is the Major Role of CMOS?

CMOS's full meaning is a kind of memory chip that is designed on the motherboard as a physical part of the Integrated Circuit board. CMOS houses the power and information and provides them to the BIOS when you turn on your computer. It reserves the configured setting and energy. If the power goes off, the CMOS is reset.
