Integrated Circuits (2)

1. A monolithic integrated circuit (also known as IC, microchip, silicon chip, computer chip or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) which has been manufactured in the surface of a thin substrate of semiconductor material.

2. Integrated circuits were made possible by experimental discoveries which showed that semiconductor devices could perform the functions of vacuum tubes, and by mid-20th-century technology advancements in semiconductor device fabrication. The integration of large numbers of tiny transistors into a small chip was an enormous improvement over the manual assembly of circuits using discrete electronic components.

3. Integrated circuits can be classified into analog, digital and mixed signal (both analog and digital on the same chip).

4. Digital integrated circuits can contain anything from one to millions of logic gates, flip-flops, multiplexers, and other circuits in a few square millimeters. The small size of these circuits allows high speed, low power dissipation, and reduced manufacturing cost compared with board-level integration. The latest server processor from Intel had 4 billion transistors on a chip.

Analog integrated circuits perform analog functions like amplification, active filtering, demodulation, mixing, etc.

5. ADCs and DACs are the key elements of mixed signal ICs. They convert signals between analog and digital formats.

6. ICs generally can be classified into analog ICs and digital ICs, according to the element’s (circuit) function. Analog ICs, like sensors, power management circuits, and operational amplifiers, work by processing continuous signals, while digital ICs like microprocessors, DSPs, and micro controllers work using binary math to process “one” and “zero” signals. However, today’s ICs often combine both analog and digital circuits on a single chip to create functions such as A/D converters and D/A converters. Such circuits offer smaller size and lower cost, but must carefully account for signal interference (see signal integrity).

7. The growth of complexity of integrated circuits follows a trend called “Moore’s Law”, first observed by Gordon Moore of Intel. Moore’s Law in its modern interpretation states that the number of transistors in an integrated circuit doubles every two years. By the year 2000 the largest integrated circuits contained hundreds of millions of transistors. It is difficult to say whether the trend will continue.
