Através do entendimento dos fenômenos da natureza, podemos entender como as coisas acontecem em nosso dia-a-dia. A Física tem grande importância para a sociedade, pois uma infinidade de equipamentos que utilizamos hoje, em nosso cotidiano (como rádios, tvs, celulares, mp3, computadores, laser, dentre outros), foram desenvolvidos utilizando conceitos e Leis da Física. É a ramo da Física que estuda os movimentos. Esse estudo está subdividido em duas partes: -a Cinemática, que estuda o movimento de corpos ou partículas sem se preocupar com as causas que dão origem ao movimento; -a Dinâmica, que estuda as causas dos movimentos. CINEMÁTICA: Partícula: é todo corpo cujas dimensões não interferem no estudo de um determinado fenômeno físico. Corpo Extenso: é todo corpo cujas dimensões interferem no estudo de um determinado fenômeno. Referencial: é um ponto fixo (ou objeto) pré-determinado, a partir do qual se pretende analisar se um corpo (ou partícula) está em movimento ou não. É indispensável para se determinar a posição de um objeto. Sistema Internacional de Unidades (S.I): é um conjunto de unidades de medida onde se adotam unidades pré-escolhidas para as grandezas físicas comprimento, massa e tempo. O padrão mais comum utilizado na Brasil é o M.K.S., sendo: comprimento → metro(m); massa → quilograma (Kg); tempo → segundo(s). Velocidade Média (V m ): é a razão entre a distância percorrida por um corpo (ou partícula) e o tempo gasto em percorrê-la. Matematicamente, podemos calcular a Velocidade Média de um corpo ou partícula utilizando: V m = ∆ ∆ ∆ ∆S , onde: Vm = Velocidade Média (m/s); ∆ ∆ ∆ ∆t ∆S = Variação da Posição (m); → corresponde à distância Percorrida ∆t = Variação do Tempo (s). → corresponde ao intervalo de tempo gasto A unidade de velocidade média no Sistema Internacional é o metro/segundo (m/s). Em Física, a letra grega ∆ significará, aqui no Ensino Médio, sempre uma Variação. Desta maneira, poderemos escrever, sempre que for conveniente, essa variação como sendo uma subtração entre os valores finais e os valores iniciais da mesma grandeza. Por exemplo: Variação do tempo (∆t) pode ser escrita matematicamente como instante de tempo final menos o instante de tempo inicial (t f -t i ). A variação da velocidade de uma partícula (∆v) pode ser escrita matematicamente como sendo a velocidade final menos a velocidade inicial da partícula (v f -v i ). Podemos aplicar esse conceito também à Velocidade Média. Fazendo isso, podemos escrever matematicamente outra forma de calcular a Velocidade Média de um corpo: v m = s f -s i , onde: vm = velocidade média (m/s); t f -t i sf = posição final do corpo (m); si = posição inicial do corpo (m); tf = instante de tempo final (s); ti = instante de tempo inicial (s).

PUF devices have a character that provides a Challenge-bit (Cb) input and generates a random Response-bit (Rb). In this work, we verified the stability of a proposed TPCA-PUF using predictive technology model (PTM). We simulate the TPCA-PUF into 4-bit with various PTM models, the tolerance of TOX and Vth is ±10%, based on PTM High Performance (HP) and Low-Power (LP) modes. The temperature varies from-40 o C to 100 o C with reference 27℃, the supply voltage is trapezoidalshaped at operating frequency of 10 MHz. The PUF evaluation metrics of the uniqueness (U) and reliability (R) (ideally 50% and 100%, respectively) are calculated to verify the PUF performances. The results of TPCA-PUF are U: 49.671% and Re: 99.51%, and consumes an energy of 3.60 fJ/bit/cycle.

It consists of a circuit board, which can be programed (referred to as a microcontroller) and a ready-made software called Arduino IDE (Integrated Development Environment), which is used to write and upload the computer code to the physical board. Arduino provides a standard form factor that breaks the functions of the micro-controller into a more accessible package. Audience This tutorial is intended for enthusiastic students or hobbyists. With Arduino, one can get to know the basics of micro-controllers and sensors very quickly and can start building prototype with very little investment. Prerequisites Before you start proceeding with this tutorial, we assume that you are already familiar with the basics of C and C++. If you are not well aware of these concepts, then we will suggest you go through our short tutorials on C and C++. A basic understanding of microcontrollers and electronics is also expected.

It is intended for use by degree and diploma students in electrical and electronic engineering and in the associated areas of integrated, manufacturing and mechanical engineering. The two most important areas of study for all electrical and electronic engineering students are those of circuit theory and electromagnetic field theory. These lay the foundation for the understanding of the rest of the subjects which make up a coherent course and they are intimately related. Texts on one of them invariably and inevitably have references to the other. In Chapter 2 of this book the ingredients of electric circuits are introduced and the circuit elements having properties called capacitance and inductance are associated with electric and magnetic fields respectively. Faraday's law is important in the concept of mutual inductance and its effects. Reference is made, therefore, to electromagnetic field theory on a need to know basis, some formulae being presented without proof. The level of mathematics required here has been kept to a realistic minimum. Some facility with algebra (transposition of formulae) and knowledge of basic trigonometry and elementary differentiation and integration is assumed. I have included well over a hundred worked examples within the text and a similar number of problems with answers. At the end of each chapter there is a series of self-assessment test questions.

In the past two decades, CMOS technology has rapidly embraced the field of analog integrated circ... more In the past two decades, CMOS technology has rapidly embraced the field of analog integrated circuits, providing low-cost, high-performance solutions and rising to dominate the market. While silicon bipolar and III-V devices still find niche applications, only CMOS processes have emerged as a viable choice for the integration of today's complex mixed-signal systems. With channel lengths projected to scale down to 0.05 μm, CMOS technology will continue to serve circuit design for another two decades. Analog circuit design itself has evolved with the technology as well. High-voltage, high-power analog circuits containing a few tens of transistors and processing small, continuous-time signals have gradually been replaced by low-voltage, low-power systems comprising thousands of devices and processing large, mostly discrete-time signals. For example, many analog techniques used only ten years ago have been abandoned because they do not lend themselves to low-voltage operation. This book deals with the analysis and design of analog CMOS integrated circuits, emphasizing fundamentals as well as new paradigms that students and practicing engineers need to master in today's industry. Since analog design requires both intuition and rigor, each concept is first introduced from an intuitive perspective and subsequently treated by careful analysis. The objective is to develop both a solid foundation and methods of analyzing circuits by inspection so that the reader learns what approximations can be made in which circuits and how much error to expect in each approximation. This approach also enables the reader to apply the concepts to bipolar circuits with little additional effort. I have taught most of the material in this book both at UCLA and in industry, polishing the order, the format, and the content with every offering. As the reader will see throughout the book, I follow four "golden rules" in writing (and teaching): (1) I explain why the reader needs to know the concept that is to be studied; (2) I put myself in the reader's position and predict the questions that he/she may have while reading the material for the first time; (3) With Rule 2 in mind, I pretend to know only as much as the (first-time) reader and try to "grow" with him/her, thereby experiencing the same thought process; (4) I begin with the "core" concept in a simple (even imprecise) language and gradually add necessary modifications to arrive at the final (precise) idea. The last rule is particularly important in teaching circuits because it allows the reader to observe the evolution of a topology and hence learn both analysis and synthesis. The text comprises 16 chapters whose contents and order are carefully chosen to provide a natural flow for both self-study and classroom adoption in quarter or semester systems. Unlike some other books on analog design, we cover only a bare minimum of MOS device physics at the beginning, leaving more advanced properties and fabrication details for later chapters. To an expert, the elementary device physics treatment my appear oversimplified, but my experience suggests that (a) first-time readers simply do not absorb the high-order device effects and fabrication technology before they study circuits because they do not see the relevance; (b) if properly presented, even the simple treatment proves adequate for a substantial coverage of basic circuits; (c) readers learn advanced device phenomena and processing steps much more readily after they have been exposed to a significant amount of circuit analysis and design. Chapter 1 provides the reader with motivation for learning the material in this book. Chapter 2 describes basic physics and operation of MOS devices. Chapters 3 through 5 deal with single-stage and differential amplifiers and current mirrors, respectively, developing efficient analytical tools for quantifying the behavior of basic circuits by inspection. Chapters 6 and 7 introduce two imperfections of circuits, namely, frequency response and noise. Noise is treated at an early stage so that it "sinks in" as the reader accounts for its effects in subsequent circuit developments. Chapters 8 through 10 describe feedback, operational amplifiers, and stability in feedback systems, respectively. With the useful properties of feedback analyzed, the reader is motivated to design high-performance, stable op amps and understand the trade-offs between speed, precision, and power dissipation. vi Preface to the Second Edition Chapters 11 through 13 deal with more advanced topics: bandgap references, elementary switchedcapacitor circuits, and the effect of nonlinearity and mismatch. These three subjects are included here because they prove essential in most analog and mixed-signal systems today. Chapter 14 is concerned with high-order MOS device effects and models, emphasizing the circuit design implications. If preferred, the chapter can directly follow Chapter 2 as well. Chapter 15 describes CMOS fabrication technology with a brief overview of layout design rules. Chapter 16 presents the layout and packaging of analog and mixed-signal circuits. Many practical issues that directly impact the performance of the circuit are described and various techniques are introduced. The reader is assumed to have a basic knowledge of electronic circuits and devices, e.g., pn junctions, the concept of small-signal operation, equivalent circuits, and simple biasing. For a senior-level elective course, Chapters 1 through 8 can be covered in a quarter and Chapters 1 through 10 in a semester. For a first-year graduate course, Chapters 1 through 11 plus one of Chapters 12, 13, or 14 can be taught in one quarter, and almost the entire book in one semester. The problem sets at the end of each chapter are designed to extend the reader's understanding of the material and complement it with additional practical considerations. A solutions manual will be available for instructors.

Two or three such satellites aptly spaced apart in the orbit provided uninterrupted service. Satellites in such an orbit with a 12 hour orbital period remained over the countries of the former Soviet bloc in the northern hemisphere for more than 8 hours. The Molniya-1 series was followed later by the Molniya-2 (in 1971) and the Molniya-3 series (in 1974). 1.3.6 International Communication Satellite Systems The Intelsat-1 satellite was followed by the Intelsat-2 series of satellites. Four Intelsat-2 satellites were launched in a span of one year from 1966 to 1967. The next major milestone vis-à-vis communication satellites was achieved with the Intelsat-3 series of satellites (Figure 1.18) becoming fully operational. The first satellite in the Intelsat-3 series was launched in 1968. These satellites were positioned over three main oceanic regions, namely the Atlantic, the Pacific and the Indian Oceans, and by 1969 they were providing global coverage for the first time. The other new concept tried successfully with these satellites was the use of a de-spun antenna structure, which allowed the use of a highly directional antenna on a spin-stabilized satellite. The satellites in the Intelsat-1 and Intelsat-2 series had used omnidirectional antennas. Figure 1.18 Intelsat-3 (Reproduced by permission of © Intelsat) The communication satellites' capabilities continued to increase with almost every new venture. With the Intelsat-4 satellites (Figure 1.19), the first of which was launched in 1971, the satellite capacity got a big boost. Intelsat-4A series introduced the concept of frequency reuse. The frequency re-use feature was taken to another dimension in the Intelsat-5 series with the use of polarization discrimination. While frequency re-use, i.e. use of the same frequency band, was possible when two footprints were spatially apart, dual polarization allowed the reuse of the same frequency band within the same footprint. The Intelsat-5 satellites (Figure 1.20), the first of which was launched in 1980, used both C band and Ku band transponders and were three-axis stabilized. The satellite transponder capacity has continued to increase through the Intelsat-6, Intelsat-7 and Intelsat-8 series of satellites launched during the 1980s and 1990s. Intelsat-9 and Intelsat-10 series were launched in the first decade of the new millennium. 1.5.4 Navigational Satellites Satellite based navigation systems are being further modernized so as to provide more accurate and reliable services. The modernization process includes launch of new more powerful satellites, use of new codes, enhancement of ground system, etc. Infact satellite based systems will be integrated with other navigation systems so as to increase their application potential. The GPS system is being modernized so as to provide more accurate, reliable and integrated services to the users. The first efforts in modernization began with the discontinuation of the selective availability feature, so as to improve the accuracy of the civilian receivers. In continuation of this step, Block IIRM satellites will carry a new civilian code on the L2 frequency. This will help in further improving accuracy by compensating for atmospheric delays and will ensure greater navigation security. Moreover, these satellites will carry a new military code (M-code) on both the L1 and L2 frequencies. This will provide increased resistance to jamming. This new code will be operational by the year 2010. The satellites will also have more accurate clock systems. Block-IIF satellites (to be launched after the Block II satellites), planned to be launched by the year 2011, will have a third carrier signal, L5, at 1176.45 MHz. They will also have larger design life, fast processors with more memory, and a new civil signal. The GPS-III phase of satellites is at the planning stage. These satellites will employ spot beams. The use of spot beams results in increased signal power, enabling the system to be more reliable and accurate, with system accuracy approaching a metre. As far as the GLONASS system is concerned, efforts are being made to make the complete system operational in order to exploit its true application potential. Another satellite navigation system that is being developed is the European Galileo system. The first Galileo satellite was launched on 28 December 2005. It is planned to launch another satellite in the near future. These satellites will define the critical technologies of the system. Following this, four operational satellites will be launched to complete the validation of the basic Galileo space segment and its related ground segment. Once this In-Orbit Validation (IOV) phase has been completed, the remaining operational satellites will be placed in orbit so as to reach the full operational capability. The fully operational Galileo system will comprise 30 satellites (27 operational and three active spares), positioned in three circular Medium Earth Orbit (MEO) planes at 23 222 km altitude above the Earth, and with each orbital plane inclined at 56 degrees to the equatorial plane. The system will be operational in the near future. All of these developments will expand the horizon of their applications to new dimensions. In fact, the future of satellite navigation systems is as unlimited as one's imagination. Navigation satellite services will improve as the services provided by the three major navigation satellite systems (GPS, GLONASS, and GALILEO) will be integrated and the user will be able to obtain position information with the same receiver from any of the satellites of the three systems.
