An integrated circuit is an electronic circuit formed on a small piece of semiconducting material, which performs the same function as a larger circuit made from discrete components. A semiconductor such as silicon can be controlled to conduct much or little. This allows making transistors that control each other.

Integrated circuits are electronic circuits formed on a small piece of semiconducting material, which perform the same function as a larger circuit made from discrete components. They are compact, and cheap and fast and more efficient than conventional circuits, and hence they are preferred over them.

Analog circuits are circuits dealing with signals free to vary from zero to full power supply voltage. This stands in contrast to digital circuits, which almost exclusively employ 'all or nothing' signals. Both the input and output signals are analog here.

Microprocessor chip, laptops and personal computer and mobiles phones, all have IC based design which makes them small and relatively cheaper.

An integrated circuit is an electronic circuit formed on a small piece of semiconducting material, which performs the same function as a larger circuit made from discrete components. Their main advantage is the small size of the circuit, which is of the order of $10^{-3}m$ to $10^{-1}m$.

An integrated circuit is a circuit in which all or some of the circuit elements are inseparably associated and electrically interconnected so that it is considered to be indivisible for the purposes of construction and commerce. These have revolutionized the electronic industry by increasing the processing speed of computers by making them reach in order of GigaHertz.

An 'integrated circuit' is an electronic circuit formed on a small piece of semiconducting material, which performs the same function as a larger circuit made from discrete components. It is also called a chip or microchip.

Integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. So, it forms a complete electronic circuit.

Moore's law states that the number of transistors in per square inch of an IC would be doubled after every two or one and a half years i.e. the memory capacity of a chip doubles every one and a half years.

Integrated circuits are electronic circuits formed on a small piece of semiconducting material, which perform the same function as a larger circuit made from discrete components. They are compact, and cheap and fast and more efficient than conventional circuits. Due to their low cost of production on large scales they are produced on industrial scale.

Integrated circuits are electronic circuits formed on a small piece of semiconducting material, which perform the same function as a larger circuit made from discrete components. They are compact, and cheap and fast and more efficient than conventional circuits, and hence they are preferred over them. However conventional circuits still have the advantage of high power handling capacity over the ICs.

Integrated chips have advantage when being used to fabricate a number of components at the same time. However when single component is being fabricated, it is advisable to fabricate components using circuit components instead of an Integrated Circuit.

Integrated circuits are used for low voltage applications. They are low power devices for use in application like microprocessor chips. 
For high voltage devices like transformers, conventional circuits are used.
