About Integrated circuits.
An integrated circuit, or IC, is small chip that can function as an amplifier, oscillator, timer, microprocessor, or even computer memory. An IC is a small wafer, usually made of silicon, that can hold anywhere from hundreds to millions of transistors, resistors, and capacitors.

Types of integrated circuits based on Number of Transistor used
1 SSI – Small scale integration.
1 to 10 Transistor.
2. MSI.– Medium scale integration.
10 to 500 tranistor.
3. LSI.- Large scale integration.
500 to 20000 .transistor
4. VLSI. – Very Large Scale integration.
More than 20000
Applications of I.C.
- Power amplifiers.
- Small-signal amplifiers.
- Operational amplifiers.
- Microwave amplifiers.
- Radio receivers.
- Computer memory.
- Computer Processors.
