TRANSCRIPT
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.
