?Unit2:1.Keywords Lesson3: semiconductors conductivity silicon GermaniumLesson4: Moore's law density unit cost Power consumption2.SummaryAfter reading lesson two, we have learned “Moore’s Law” summed up the pace of progress in information technology. In the past 40 years, the computer from the mystery of the monster has becoming an indispensable tool for the majority of people. Information technology from the laboratory into the countless ordinary family. Internet link to the world, multi-media audio-visual equipment enrich everyone's lives. “Moore’s Law “describes the number of transistors that can be placed inexpensively on an integrated circuit has increased exponentially, doubling approximately every two years. Several measures of digital technology are improving related to Moore's law, including the size, cost, density and speed of components. Intel has kept that pace for nearly 40 years. Today, they continue to help move the industry forward by delivering: A worldwide silicon fab network with seven high volume fabs,and the world's first 32nm silicon technology on-target for delivery in 2009 . The world's first two billion transistor microprocessor delivered in next-generation Intel? Itanium? processors codenamed Tukwila.Revolutionary technologies on a chip, like hafnium-based high-k metal gate in production today .Finally Advanced research into tri-gate transistors and silicon nanotechnology.Unit3:1.Keywords Lesson5:resistor, capacitor, inductor, passive component, electric charge ,wireLesson6:diode, minority carrier, p-n junction, depletion region, the threshold voltageLesson7:Bipolar transistor, field-effect transistor, channel2. SummaryA transistor is a linear semiconductor device that controls current with the application of a lower-power electrical signal. Transistors may be roughly grouped into two major divisions: bipolar and field-effect transistor. Bipolar transistor restrict the amount of current that can go through them according to a smaller, controlling current. But for the field-effect transistor, the conductivity which is the region between source and drain of channel is controlled by the potential of the gate terminal. This is the majorty difference of two transistor. There are three ways of connecting a transistor, depending on the use to which it is being put. The ways are classified by the electrode that is common to both the input and the output. They are called: (a) common-base configuration(b) common-emitter configuration(c) common-collector configuration. The effect of changing one or more of the various voltages and currents associated with a transistor circuit can be shown graphically and these graphs are called the characteristics of the transistor. As there are five variables (collector, base and emitter currents and voltages across the collector and base and emitter and base) and also three configurations, many characteristics are possible.Unit4:1.KeywordsLesson8:Finite gain 。省略部分。for lossy compression, like graphics, audio, and video. Lossy compression necessarily reduces the quality of the file to arrive at the resulting highly compressed size, but depending on the need, the loss may acceptable and even unnoticeable in some cases. unit14:1.KeywordsLesson38:PC, Web browser, optical disc drive, expansion slot Lesson39:extraction, fingerprint, computerizeLesson40:embed, SOPC, IP, PIO2.SummaryPC consists of some hardware. Hardware is a basic of PC. Computer software, including operating system, applications, is a general term used to describe a collection of computer programs, procedures and documentation that performs some tasks on a computer system. PC are divided into many types are workstation, desktop computer, single unit, nettop, laptop, netbook, tablet PC, Ultra-Mobile PC, Home Theater PC, and Pocket PC. The personal computer is the darling of the decade. The global personal computer shipments were more and more in the year 2007 than in 2006. With the price of PC is lower and the capability of it is higher than before, the people are buying personal computers in record numbers. Today's junior high, high school and college students will enter the job market during the next decade thoroughly familiar with terminal keyboards and totally comfortable with a work station on their desks. Unit15:1.KeywordsLesson41:EDA; MATLAB; Simulink; simulator; SPICE; PSPICE; netlist; schematics; ASIC; full-custom; logic design and verification; timing-driven2.SummaryIn unit14, we have learned something about the EDA tools. EDA is short for electronic design automation. Three kinds of EDA tools have been introduced, namely MATLAB, PSPICE and Cadence, every one of which is a tool capable of accomplishing various tasks. MATLAB is a kind of mathematic software developed by Math Works Company in USA. It is a high level technical language and interactive environment, widely used in algorithm development, data visualization,data analysis, and numerical calculation. MATLAB consists of two parts: one is MATLAB, and the other is Simulink. PSPICE is a graphical entry version of SPICE, which means that a schematic is drawn on the screen, and the computer derives the NETLIST from the schematic. As a result, PSPICE uses the same numerical algorithms that SPICE uses and will still run SPICE files. The graphical nature of PSPICE provides the results on a graph instead of presenting a table of output data as SPICE did.Cadence is a large-scale EDA software, with which you can achieve almost all aspects of electronic design, including ASIC design, FPGA design and PCB board design. Cadence has absolute advantage in schematic design, circuit simulation, automatic placement and routing, layout design and verification.With the scale of the integrated circuits dramatically increasing, we cannot do without EDA tools.Unit16:1.
