Integrated circuitry. Topology of integrated circuit

Integrated circuits - miniature microelectronic product, whose elements are inextricably linked structurally, technologically and electrically. Performs some transformation function and a high packing density of electrically interconnected elements and components, which is a whole in terms of testing requirements and operation.

Analog and digital integrated circuits

Electronic circuits are divided into two classes - analog and digital. Schemes first type designed to handle analog signals, circuits of the second type - to work with a digital signal. Digital electronic circuits are gradually replacing analog even traditional application areas, such as in television.

Examples of integrated circuits

The topology of integrated circuits

• The topology of integrated circuits - is fixed on a physical medium spatial and geometric arrangement together elements of integrated circuits and connections between them.

Classification of integrated circuits• By way of association are distinguished:

• Semiconductor chip - all elements and connections between elements are made on a single semiconductor chip (eg, silicon, germanium, gallium arsenide, hafnium oxide).

• Film integrated circuit - all elements and compounds in the form of films:

• thick-film integrated circuit;

• thin film integrated circuit.

• Hybrid chip - in addition to a semiconductor crystal containing little OEM diodes, transistors and (or) other electronic components placed in one housing.

The degree of integration

Small integrated circuit (MIC) - up to 100 elements in crystalthe average integrated circuit (CIC) - up to 1000 items in the

crystal,large-scale integrated circuit (LSI) - up to 10 thousand.

elements in the crystal,very large scale integrated circuit (ASIC, VLSI - English. Very-

large-scale integration) - over 10 thousand. elements in the crystal. [1]

Very-large-scale integration - integration degree microprocessor integrated circuits with more than 100,000 members [2]

Used in a variety of analog and digital elements of automation, data acquisition systems.
