which a complete electronic system fits in a single integrated circuit. At that moment, the System on Chip was born. This trend in electronics (and computers) can be described in evolution periods. From 1960 to 1975, it was the mainframe computer age, where integrated circuits where designed looking only on performance. In the next 15 years, the network age occurred; in this time the VLSI technologies evolved considerably because the main design objective was cost/performance oriented. Finally

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
term used to describe the evolution of computing, i.e. in other words it means improvement in the field of computer. There are six types of generation of computers: First Generation: Vacuum Tube Second Generation: Transistor Third Generation: Integrated Circuit Fourth Generation: Microprocessor Fifth Generation: Parallel Processing Sixth Generation:Reduced Instruction Set Chip (RISC) FIRST GENERATION1940-1956: Vacuum Tubes The first generation of computers used vacuum tubes(electric tubes about the
generally had only one purpose and could never be reprogrammed to do anything but what the original design had entailed. This was true for the Atanasoff-Berry computer, the first digital computer, as well. However, this computer ran using electronics, used binary number representation for its calculations, and separated computation and memory (O 'Regan). These three points were essential for all proceeding designs in digital computing. The first programmable digital computer was completed in 1946 by a team
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
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
Computer is an advance electronic devices , in this modern age computer playing an important role in our daily life. For better or worst , the computer affecting all aspect of our society . Generally , most of the people only know that computer used for calculation or computation ,but actually its more than that , precisely computer is an electronic device for performing arithmetic and logical operation device or a flexible machine to process data and converts it into information .Today , computer
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
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,
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)

and can perform calculations much faster and more accurately than any team of human computers ever could. Charles Babbage is the father of computing after his invention and concept of the Analytical Engine in 1837. With a basic flow control, and integrated memory, the first general purpose computer concept was born. It was later that, Charles’ son Henry Babbage completed a portion of this machine and the computer was able to perform basic calculations. Having no invention of a computer, the Babbage
commercially available or developed in any realistically usable way like silicon is. Currently we have been able to successfully prototype a variety of methods for non-traditional silicon based technologies such as 3D chip stacking and multi-core processor design. This paper will discuss the benefits of utilizing non-traditional silicon and how the other “solutions” to the end of traditional silicon are not developed to the point of being a real solution. The other “solutions” are DNA computing, Optical computing
