An Integrated Circuit is a chip or a microchip on which thousands of transistors, capacitors, resistors are fabricated. It can be an Amplifier IC, a timer IC, a waveform generator IC, a memory IC or a Microcontroller IC. It can be an analog IC with a continuous variable output or a Digital IC operating at a few defined layers. The fundamental building blocks of Digital ICs are the logic gates.

Classification of ICs (Integrated Circuits)
Below is the classification of different types of ICs basis on their chip size.
- SSI: Small scale integration. 3 – 30 gates per chip.
- MSI: Medium scale integration. 30 – 300 gates per chip.
- LSI: Large scale integration. 300 – 3,000 gates per chip.
- VLSI: Very large scale integration. More than 3,000 gates per chip.
