Circuits are the basic building blocks of all electrical and electronicsystems. These systems generate, store, and transmit information, processdata, perform computations, make measurements, and transfer energy bymeans of electrical signals. A state-of-the-art microprocessor, at theheart of any modern computer, is essentially one large circuit containingseveral million transistors, housed in a small package. On the otherend of the scale, the entire electric power distribution network ofthe U.S. is one huge circuit spanning distances of thousands of miles.

Circuits are usually classified as digital or analog. A digital circuit isa circuit in which the signals are quantized into discrete levels, typically two.For example, in positive binary logic circuits a high voltage (above a given threshold)represents a "one," and a low voltage (below a given threshold)represents a "zero."With such circuits, binary arithmetic can be performed, and various other signalprocessing functions can be accomplished. An analog circuit is a circuit in whichthe voltages and currents are not categorized into quantized levels. In many casesboth digital and analog circuits are used in the design of an electrical or electronicsystem.

Modern circuits are integrated, in the sense that hundreds of thousands, oreven millions, of transistors are fabricated and interconnected on a single pieceof silicon, called a chip. Advances in integrated circuit technology over thepast few years have led to the development of powerful hand-held computers, electronicwatches, sophisticated electronic cameras and games, desk-top computers, supercomputers,sophisticated medical instrumentation, and powerful guidance and communicationsystems, among other hi-tech systems. In spite of all this progress, we will continueto see integrated circuit technology make rapid and significant advances in theareas of instrumentation, communication, computation, and control.

In order to learn about integrated circuits, one has to study fabricationprocesses, circuit theory, circuit design, and system design, all in an integratedfashion.
