Devices used in applications such as these are constantly decreasing in size and employing more complex technology. It is therefore essential for engineers and students to understand the fundamentals, implementation and application principles of digital electronics, devices and integrated circuits. This is so that they can use the most appropriate and effective technique to suit their technical need.

Electronics and computer engineering is a scientific and technical field in which electronic and computer systems are studied and their use. They are related to the technical professions within which electronic devices, systems, and computer programs are realized. The past half-century has been greatly marked by the development of electronics, computing, and their application in communications, medicine, and industry. This field has become the fundamental technical infrastructure of modern society. Today, there is almost no electronic device that does not use an electronic computer, and there is also not a single computer that is almost exclusively made of electronic components. This article explores the need for electronic components in digital computing.
One of the digital communication mediums is an optical fiber with data rates of 100 Gbps. In wireless area networks (WAN), an optical switch and multiplexing schemes are allowed to speed up the limits. Examples of optical sources include injection laser diode (ILD), and light-emitting diode (LED). The optical fiber cable is used for data and voice communication. The internet world runs using the components like modems, telephone lines, and dial-up services [3, 4]. The future internet requires millions of digital machines, devices, robots, sensors, digitized, smart objects, and the Internet of Things (IoT). The working environments require a set of electronics that includes actuators, processors, controllers, displays, projectors, digital cameras, systems, communicators, gateways, smartphones, and high-definition displays. Information technology involves the latest innovations in different fields such as soft and hard computing, microprocessors, microelectronics, cloud computing, telecommunications, optoelectronics, fiber optics, and semi-conductors. These findings enable the storage and processing power of a large amount of information over the wireless and wired network channels.

Digitization transforms global flows by vastly reducing marginal production and distribution costs in three ways. The first is the creation of purely digital goods, in both the B2B and B2C realms. The volume of digital consumer goods, from music to movies, transported and reproduced around the globe continues to soar. Apps that allow consumers to purchase virtual goods and digital services on mobile devices have become a significant industry. For businesses, digitization is transforming even physical flows of people into virtual flows, enabling remote work through tools for global collaboration. In some manufacturing sectors, it is now possible to ship a digital design file for 3-D printing and then make the product where it will be consumed instead of producing centrally and shipping the physical goods.
A very important limitation of high-speed analog-todigital converters (ADCs) is their power dissipation. ADC power dissipation has been examined several times, mostly empirically. In this paper, we present an attempt to estimate a lower bound for the power of ADCs, based on first principles and using pipeline and flash architectures as examples. We find that power dissipation of high-resolution ADCs is bound by noise, whereas technology is the limiting factor for low-resolution devices. Our model assumes the use of digital error correction, but we also study an example on the power penalty due to matching requirements. A comparison with published experimental data indicates that the best ADCs use about 50 times the estimated minimum power. Two published ADCs are used for a more detailed comparison between the minimum bound and todays designs. 041b061a72
