What are some electronics that use semiconductors?

Many digital consumer products in everyday life such as mobile phones / smartphones, digital cameras, televisions, washing machines, refrigerators and LED bulbs also use semiconductors.

Why we use semiconductor in the electronics purposes?

We use semiconductor because we wish a material that you can control easily the conductivity. And for this purpose, semiconductors are the best one. It is not so easy to control the conductivity of isolator and conductors. The transistor works as a switch, that is close (low resistance) or open (high resistance).

Why semiconductors are important in electronics?

In a process called doping, small amounts of impurities are added to these pure elements, causing large changes in the conductivity of the material. Due to their role in the fabrication of electronic devices, semiconductors are an important part of our lives. Imagine life without electronic devices.

What are semiconductor devices used for?

Semiconductors are employed in the manufacture of various kinds of electronic devices, including diodes, transistors, and integrated circuits. Such devices have found wide application because of their compactness, reliability, power efficiency, and low cost.

What are the applications of semiconductor devices?

Applications of Semiconductor Devices. They are used in the designing of logic gates and digital circuits. These are used in microprocessors. They are also used in analog circuits such as oscillators and amplifiers. Used in high voltage applications.

Where can I find lectures on analog electronics in India?

What are the advantages of MOSFET in digital signal processing?

The major success of MOSFET in digital signal processing comes from the invention of CMOS logic circuit. The biggest advantage of this structure is that there is no static power loss in theory, and only when the switch of logic gate there is current passing through. The most basic member of the CMOS logic gate is the CMOS inverter.

What is the material of gate electrode of MOSFET?

The gate electrode of the early MOSFET used metal as its material, but with the development of semiconductor technology, polysilicon has replaced metal as the material of gate electrode of MOSFET. In processor, the Polysilicon gate is no longer the mainstream technology.
