The prime goal of this article is to discuss about integrated circuits. Integrated circuit, also identified as IC, chip, or microchip, is a small electronic circuit which was man-made on the surface of a thin semiconductor substance. It is used in nearly all the helpful electronic apparatus these days such as computers, microwaves, phones, and other digital appliances. It can be separated into digital, analog and varied signal. Digital chips are tiny in size, fast velocity, low power loss, and cut the cost.
