4. Very Large Scale Integration
Introduction to VLSI
Very Large Scale Integration
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip.
VLSI began in the 1970s when complex semiconductor and communication technologies were being developed.

5. Advantages of VLSI Reduces the Size of Circuits.
2. Reduces the effective cost of the devices.
3. Increases the Operating speed of circuit.
4. Requires less power than Discrete components.
5. Higher Reliability
6. Occupies a relatively smaller area.

6. Applications of VLSI
In today's world VLSI chips are widely used in various branches of Engineering like:
Voice and Data Communication networks
Digital Signal Processing
Computers
Commercial Electronics
Automobiles
Medicine and many more

7. Types Of Digital System
Combinational Circuit
Sequential Circuit

8. Combinational Circuit
Combinational logic is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only.

9. Sequential Circuit
Sequential logic is a type of logic circuit whose output depends not only on the present value of its input signals but on the sequence of past inputs
