You know the invention of the transistor has been the decisive factor in the development of VLSI technology. Before you learn about VLSI technology, it is important that you get a general understanding of the development of electronics.
Electronics deals with circuits that include different active and passive components. In the original sense, the components used in electronic circuits, like that of diodes, consisted of vacuum tubes known as discrete components. Later, when the Solid-State Device (SSD) got invented, the components were formed up of semiconductors. Vacuum tubes had the difficulty of their size, power and even that of dependability. Of course, once you join up a class or course like the Vlsi course in Bangalore, you can get proper knowledge about everything.
What do you mean by the Integrated circuit?
The integrated circuit is the type of circuit wherein all passive and active components get manufactured on a single chip. In the initial times, the integrated chip might only possess a few components. As the days passed by, the devices turned out to be more complex and needed more circuits that made them huger. Such technology has not only helped diminish the size of devices but has even enhanced their speed. Relying on the number of components (transistors) to mix, they have got classified into three categories: MSI, SSI, LSI, VLSI, ULSI, and even that of GSI.
Small scale integration (SSI):
In this type of technology, 1 to 100 transistors got manufactured on a single chip. As an example, Gates, Flip-flops.
Medium-scale integration (MSI):
By making uses of this technology, one hundred to one thousand transistors got integrated into a single chip. For example, you can think about 4-bit microprocessors.
Large scale integration
Speaking of this technology, the one thousand -ten thousand transistors could be integrated on a single chip. As an example, 8-bit microprocessors, RAM and ROM
Very-large-scale integration (VLSI):
Finally, in this technology, ten thousand-one million transistors might be adapted, for example, 16-32-bit microprocessors.
Integration on a very large scale (ULSI):
In this type of technology, one to ten million transistors might get accommodated. For example, special-purpose registers.
What is a VLSI course and what are its uses?
As you have already seen, VLSI technology is a technology with help of which 10000-1 million transistors can easily be manufactured on a single chip. Now, if you are thinking what is the need to manufacture so many transistors on a single chip?
Well, in the age of vacuum tubes, the size of electronic devices was vast. It demanded more power, dissolute more heat and was not as dependable. It was, hence, certainly essential to diminish the size of these devices and their heat debauchery. After SSDs got invented, the size and heat generated by the devices have been meaningfully reduced, but over the days, the demand for additional features in electronic devices has enhanced, which has made the devices a lot more voluminous and complicated. It has given birth to the invention of technology that might manufacture more components on a single chip. As the requirement for additional features in electronic devices has risen, VLSI technology has grown extensively.
Thus, you can check out a suitable course in the VLSI institutes in Bangalore and get the needed skills in this line for a promising future!
