electronics can be attributed to the invention of the integrated circuit. These are also commonly referred to as “microchips” and have been refined since they were invented to become smaller and more powerful. Integrated circuits are one of the greatest inventions of last century due to its profound influence on technology through the miniaturization and optimization of electronics. To understand the monumental influence integrated circuits have in technology, one must understand what kind of technology
INTEGRATED CIRCUITS 1. INTRODUCTION An integrated Circuit also known as an IC or a chip, is a set of electronic circuits and components containing many diodes, transistors and resistors etc fabricated on a small plate of semiconducting material like silicon. Actually it s a miniaturized form of electronic circuit. It is called as an ‘integrated circuit’ as all the components and circuits including base material are etched in a small piece of semiconducting plate. Its not like an assembled device
Whether you’re a student, gamer, physicist, accountant, or even a newborn baby; computers play a very integral role in all our lives. However, most people seem to take them for granted. Even though computers have only been around for about a hundred years, it’s hard to believe we once lived without them. So, how is that we went from computers the size of an apartment to computers that fit in a watch? Transistors! Transistors are the fundamental components in modern electronic devices (e.g., computer
The Integrated Circuit: The Evolution of an Electronic Miracle The microprocessor evolved over the course of many years of research, and people all over the world enjoy the benefits of this electronic miracle. It is difficult to think of anything that has affected modern life more than this invention.

This craving for proficiency and a strong will to enhance my professional skills have motivated me to take a step further by choosing to pursue Graduate studies in the discipline of Electrical Engineering at your esteemed University. From my school days I had the curiosity of knowing
DEVELOPMENT OF COMPUTERS The first generation of computer which is from the year 1945 has been relatively large in size and very expensive due to the technology that we have back then. Goes by the name “Colossus”, it was the very first electronic computer developed. It is programmable, digital, electronic, computing devices. The vacuum tubes or known as thermionic valves is used to perform calculations. It serve as purpose to solve mathematic problem faced by the British military during World War
point B. The information is transmitted from one circuit to another by using electronic currents. However, the logic sequences that have been incorporated into the electrical circuit is what distinguishes digital electronics from the electronic devices from the past. Binary logic, also known as Boolean theory, implements a base two-value logic system of “true” and “false” to transport information through electric signals. The electronic gate (circuit) is the source of what makes the electronics work
Computer generations are characterized by the technology that computers used at the time. Each generation is marked by a technological development that made a large impact on the design or use of computers. The first four generations of computers, from the 1940s until now, were based on the physical technology used in the devices, but the fifth generation is based on the capabilities of computers. While every generation of computers impacts society, the fifth generation, artificial intelligence,
Intel was founded by Gordon E. Moore in 1968. Mr. Moore was a physicist and a chemist. He also meets Robert Noyce, again another physicist and co-creator of integrated circuitry. After they both had left Fairchild Semiconductor in the 1980’s. Intel was run by a chemical engineer by the name of Andy Grove. Andy Grove today is considered to be one of the company’s essential businesses and considered strategic leaders. As the year of 1990 came to an end, Intel had become one of the largest and by far
As transistors get smaller and smaller, silicone transistors are shrinking rapidly to nearly atomic scale. As silicone transistors reach that size, it starts to become ineffective. Transistors has reached a saturation limit, where if made smaller electrons cannot be stopped from source to drain. Graphene now comes into the pictures. Graphene, is the hot topic that every physicists, material scientists, and electrical engineers have been talking about. Why did it garner such popularity in the scientific

Introduction 1.1 Why silicon integrated photonics? The observation by Gordon Moore in 1965 (now universally referred to as Moore’s law) that the number of transistors on an integrated circuit would double every couple of years has become a beacon that continues to drive the electronics industry [1]. Integrated circuits have grown exponentially from the 30-transistor devices of 1965 to today’s high-end microprocessors exceeding 500 million transistors integrated on a silicon chip the size of your
Computers have undoubtedly improved life in many respects, but they have not always been so easy to work with, nor so widespread. Changes in the computer came about from technological advancement, as well as necessity of performance. With a world changing so quickly and getting bigger each day, it’s no wonder systems needed to be implemented to keep up with the fast pace of an evolving society. The twentieth century was a time of rapid technological progression, spurred by globalization, conflict
What Are The Computer Generations First Generation (1940-1956) Vacuum Tubes The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, they generated a lot of heat, which was often the cause of malfunctions. First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform
Many different approaches are used to reduce power consumption at the circuit level design. Some of the main techniques are Transistor Sizing, Voltage Scaling, Voltage Islands, Multiple Threshold Voltages and Power Gating. There is a negative effect with each power optimisation technique used at the expense of performance or area. Rabaey (1996) states that Transistor Sizing (TS) technique is used to adjust the size of each transistor (smallest element in the digital system) or gate (group of transistors)
has led to a need for low-cost EDGE mobile solutions. The implementation of RF circuits on the nanoscale digital CMOS process with no or minimal process enhancements is one of the key obstacles limiting the complete single-chip integration of cellular radio functionality with digital baseband for mass production. The key challenges for the RF integration in nanoscale CMOS include non-linearity of devices and circuits, device mismatches, process parameter spread, and the increasing potential for self-interference
