Integrated circuits are miniature microelectronic products whose elements are structurally and electrically interconnected on a single semiconductor chip or substrate. They perform transformation functions with a high density of interconnected components. Integrated circuits can be analog or digital, with digital circuits increasingly replacing analog ones. They are classified based on the integration method, degree of integration, and application. Very large scale integrated circuits can have over 100,000 components on a single chip and are used in applications like microprocessors and data acquisition systems.
2. 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.
3. 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.
5. 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.
6. 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.
7. The degree of integration
Small integrated circuit (MIC) - up to 100 elements in crystal
the 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.
