The driving force behind the introduction to VLSI was the invention of the transistor. Firstly, what are electronics? Electronics primarily deals with circuits. It includes both passive and active components. Originally, the first components that were utilized in electronic circuits were built up of vacuum tubes; they were known as discrete components. Parts were later made up of semiconductors with the arrival of the SSD, or the Solid State Device. Vacuum Tubes had to be dropped because of their size and space occupancy. They were also slow and used a lot of power.
The Integrated Circuit
The Integrated Circuit consists of single-chip, where all the passive and active parts were placed. Originally, only a few transistors were being put on an IC. With the advancement in technology, however, more and more components had to place on the IC.
The devices became complex, the number of circuits became more confusing and bulky. A new technology called the Integration Technology came into existence which helped maintain the physical size of the IC, but also include more and more components. To learn more about IC, one can join VLSI Training In Delhi. The IC’s were categorizes depending on the number of components it could hold. They are:
- SSI (Small Scale Integration) – A maximum of 100 transistors can fabricate on one single chip.
- MSI (Medium Scale Integration) – 100-1000 transistors could now accommodate on one single chip, microprocessors for example.
- LSI (Large Scale Integration) – Around 10000 transistors can place on a single chip.
- VLSI (Very Large Scale Integration) – Devices like 16-32 bit microprocessors can have up to 1 million transistors on a single chip.
- ULSI (Ultra Large Scale Integration) and GLSI (Giant Large Scale Integration) – For special purpose registers and embedded systems.
