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.

Atomic Force Microscope

Atomic Force Microscope: Principle, Parts, Uses The atomic force  microscope  (AFM) is a type of scanning probe microscope whose primary roles include measuring properties such as magnetism, height, friction. The resolution is measured in a nanometer, which is much more accurate and effective than the optical diffraction limit. It uses a probe for measuring and collection of data involves touching the surface that has the probe. An image is formed when the scanning probe microscope raster-scans the probe over a section of the sample, measuring its local properties concurrently. They also have piezoelectric elements, which are electric charges that accumulate in selected solid materials like  DNA , biological proteins, crystal, etc, to enable tiny accurate and precise movement during scanning upon an electric command. The Atomic Force Microscope was invented in 1982, by scientists working in IBM, just after the invention of the Scanning tunneling Microscope in 1980 by Ge...

Resonant Tunneling Diodes (RTD)

Image
Concept of Resonant Tunneling An interesting phenomena occurs when two barriers of width a separated by a potential well of a small distance 𝐿 as shown in fig. This leads to the concept of resonant tunneling. Fig.: Double barrier junction with no applied bias.   The barriers are sufficiently thin to allow tunneling and the well region between the two barriers is also sufficiently narrow to form discrete (quasi-bound) energy levels. The transmission coefficient of the double symmetric barrier becomes unity. (ie., T = 1) , when the energy of the incoming electron wave ( 𝐸 ) coincides with the energy of one of the discrete states formed by the well. Thus, transmission probability of the double symmetric barrier is maximum; hence, the tunneling current reaches peak value when the electron wave's energy is equal to the well's quantized energy state. This phenomenon is known as resonance tu...
