microelectronic products are ubiquitous. Simply, they are everywhere and applications of the industry average. It seems that no area in which technology has not changed. In creating a pyramid of technology, microelectronics is positioned at the level of the mountain. His progress to other technologies. E 'correct to say that if there are innovations in microelectronics, the ICT sector is stable and eventually fade away in style. The products are available in different sizes andForms of motor control imperceptibly the "toy train" to the sophisticated microchip provided in critical life-saving tools used in hospital operating rooms.
microelectronics industry (or rather, the electronics industry) has developed in recent decades. The age of the pipes before Shockley invent the transistor at Bell Labs. This was combined with the use of discrete (external) threads of capacitors, resistors, diodes and other components to form a circle. The problemsand limits of this "trap" PCBs were evident. With these threads, the problems of noise (capacitive, inductive, etc.) are exacerbated. The result was a low-power electronic systems.
Programmable Logic Controller
Around 1957, thought a Texas Instruments engineer Jack Kilby understand how the circuits without the need for external lines that can affect performance. He could not help thinking of a way to make all the components, resistors, transistors, capacitors, etc. on the same chip(Substrate, or simply turned a piece of silicon, which forms the circuit model, cut them apart, and you have chips). In other words, using the processes of production of all components for the manufacture of integrated circuits and eliminates the need to separate their production (as in discrete systems) and then welded together after wire. His idea was to give him a Nobel Prize, has transformed the electronics industry.
Not only is his idea to help improve performance, but alsoreduces the production costs of the systems. It makes sense because everything was almost at the same time 'with a better control of processes, technologies and other topics that may give from time to time, when all units must be produced individually. The products are more compact than any 'one of the components and packaged the same way. In most cases the cost of developing an IC (integrated circuit), the 100-component was the cost of the competition containsDevelopment of a component. Before integration, the costs of 100x.
Kilby's invention helped advance the field and gave us a new microelectronics industry. The transition from electronics to microelectronics with the small size of components used in the art systems. Transistor sizes are usually in microns (10 ^ -6) data. We are in the nanometer range, move now, as in a few years, the main dimensions of a few nanometers dominatedScheme for art developed. Nano! Sound familiar?
But let's not get carried away by history. With the advent of integrated circuits and the subsequent development of CMOS (Complementary Metal Oxide Semiconductor) technology, there was a considerable success in the number of application specific integrated chip (ASIC) have been. (I'll explain in stages: CMOS is a type of transistor that works submitted to dynamic effects (more on that later) is a type of ASIC chip o.Microchip has been designed with a specific function or application, contracts with programmable gate arrays (FPGAs) that can be programmed for different applications). Interestingly, FPGA or programmable logic controllers integrated circuits that can be used. The design of the integrated circuit is exciting, but it is extremely knowledge intensive. It requires the mastery.
Integrated circuits include the circuits, the millions of transistors and other circuits canObjects on a single chip (one piece of silicon, the active devices and interfaces, input and output) files. They are listed on a special semiconductor materials with silicon and gallium arsenide (GaAs), the most common. Its development is an important milestone in the history of modern industry has spurred a revolution in computing power through a long development of the performance, cost and density gains with the balance.
Amazingly, these circuits that are made with different technologies.But over time, the CMOS industry and in fact the most widely used method of choice. Its major advantages over other technologies is the easy integration of circuit components and low static power consumption. This is the main technique for analog-digital converter, microcontroller, FPGA (a chip that contains a set of identical cells connected by programmable), microprocessors and many others make the service during the development of entertainmentHardware. The continuous improvement has led gadget game miniaturization, higher performance, more efficient battery management for battery-powered devices, cost, hardware ergonomics.
chip could be the signal digital, analog or mixed (a combination of analog and digital). While the chip includes digital logic level of the concept of 1 and 0, the analog signal on a continuous basis. More over, the sequencing and timing of communication on the chip aredone with the use of globally distributed clocks for synchronous designs or local variables handshake for asynchronous designs. Between these two methods is the first most common method. However, the delay questions, the complexity of management and clock distribution, which may limit on-site synchronous chip performance with an acceptable degree of reliability of the technology is smaller, has stimulated interest in the study of asynchronous systems.
Asynchronous chipknown as time-course circuit since they do not use clocks, but use local variables for the functions of handshake requests and confirmations. Asynchronous digital system design contains a completely different concept than the synchronous version compared. The idea of clockless system makes a lot of design parameters that must be pursued as applications and recognition signals generated and transmitted. The first phase of development of the asynchronous system isInterest, because enormous digital computer "code" level of abstraction describes the system.
