the Benefits of a Digital Circuit Design?

Integrated circuits were first introduced during the 60s and some of these early creations used as little as 100 transistors only in their complete design. These were known as SSI or Small Scale Integrated circuits and MSI or Medium Scale Integrated circuits. However, during the 90s a major transformation came around and LSI or Large Scale Integrated circuits were formed. These housed a few thousand transistors and quickly gained prominence in mass usage.

What are the Different Types of Circuits Used in a Transistor?
VLSI or Very large Scale Integrated circuits were used around the globe during the early 2000s and they house as many as 100,000 transistors for greater benefit. This arrangement was modified over a course of time and the current Digital Circuits we use consist of nearly 1,000,000,000 transistors. Now the primary question is how can an engineer work on a circuit that consists of a few Million transistors?

You should quickly draw your attention to the fact that all modern digital circuits are based on the three Logic Gates, namely AND, NOT and OR. Digital circuits can also be formed using NAND and NOR Logic Gates, each of which contain a maximum of four transistors. Hence, upon classifying Logic Gates, their functionality increases. Various technologies have been developed since the 90s and have been in use and one such example is TTL or Transistor-Transistor Logic.
