Electronic circuit simulationElectronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. Simulation software allows for modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many colleges and universities use this type of software for the teaching of electronics technician and electronics engineering programs. Electronics simulation software engages its users by integrating them into the learning experience.
Field-programmable gate arrayA field-programmable gate array (FPGA) is an integrated circuit designed to be configured after manufacturing. The FPGA configuration is generally specified using a hardware description language (HDL), similar to that used for an application-specific integrated circuit (ASIC). Circuit diagrams were previously used to specify the configuration, but this is increasingly rare due to the advent of electronic design automation tools. FPGAs contain an array of programmable logic blocks, and a hierarchy of reconfigurable interconnects allowing blocks to be wired together.
Réveille-matinthumb|Un réveille-matin mécanique.|173x173px Un réveille-matin (également écrit réveil-matin et souvent abrégé en réveil) est un système qui émet un son à une heure prédéterminée. On l'utilise généralement pour se réveiller le matin, d'où son nom. Il peut s'agir d'un appareil destiné à cet usage, généralement une horloge, ou d'autres appareils ayant une fonction réveille-matin tels que : la montre, le téléphone mobile, l'ordinateur, la télévision, la radio Platon (428–348 av. J.-C.
Gravure sècheLa gravure sèche (dry etching) est un ensemble de technique de gravure des semi-conducteurs en exposant le matériau à un bombardement d'ions (généralement sous forme de plasma). Elles se distinguent des méthodes de gravures chimiques classiques qui utilisent des solutions réactives. Parmi les gravures sèches, on compte : la gravure au plasma la gravure ionique réactive (RIE) La gravure sèche est apparue dans les années 1960 et a été inventé par Stephen M.Irving qui a également inventé les procédés de gravure par plasma.
System busA system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and although popular in the 1970s and 1980s, more modern computers use a variety of separate buses adapted to more specific needs.
Computer towerIn personal computing, a tower is a form factor of desktop computer case whose height is much greater than its width, thus having the appearance of an upstanding tower block, as opposed to a traditional "pizza box" computer case whose width is greater than its height and appears lying flat. Compared to a pizza box case, the tower tends to be larger and offers more potential for internal volume for the same desk area occupied, and therefore allows more hardware installation and theoretically better airflow for cooling.
Circuit intégré à signaux mixtesA mixed-signal integrated circuit is any integrated circuit that has both analog circuits and digital circuits on a single semiconductor die. Their usage has grown dramatically with the increased use of cell phones, telecommunications, portable electronics, and automobiles with electronics and digital sensors. Integrated circuits (ICs) are generally classified as digital (e.g. a microprocessor) or analog (e.g. an operational amplifier). Mixed-signal ICs contain both digital and analog circuitry on the same chip, and sometimes embedded software.
Pipeline (computing)In computing, a pipeline, also known as a data pipeline, is a set of data processing elements connected in series, where the output of one element is the input of the next one. The elements of a pipeline are often executed in parallel or in time-sliced fashion. Some amount of buffer storage is often inserted between elements. Computer-related pipelines include: Instruction pipelines, such as the classic RISC pipeline, which are used in central processing units (CPUs) and other microprocessors to allow overlapping execution of multiple instructions with the same circuitry.
Simple programmable logic deviceA simple programmable logic device (SPLD) is a programmable logic device with complexity below that of a complex programmable logic device (CPLD). The term commonly refers to devices such as ROMs, PALs, PLAs and GALs. Simple programmable logic devices (SPLD) are the simplest, smallest and least-expensive forms of programmable logic devices. SPLDs can be used in boards to replace standard logic components (AND, OR, and NOT gates), such as 7400-series TTL. They typically comprise 4 to 22 fully connected macrocells.
Procédé planardroite|vignette| Photo de puce annotée d'une puce Fairchild Le procédé planar est un procédé de fabrication utilisé dans l'industrie des semi-conducteurs pour fabriquer les parties élémentaires d'un transistor et connecter ensemble les transistors ainsi obtenus. C'est le processus principal de fabrication des puces de circuits intégrés en silicium. Il utilise les méthodes de passivation de surface et d'oxydation thermique.
