Categories
of semiconductor components (Integrated circuit families)
•Integrated circuits are made from
semiconductor material
•These are divided into three main categories
A) Analog components
B) Mixed
signal components
C) Digital components
According to various applications they are
further classified as
1) Standard components
2) Semicustom components
3) Custom parts
Each main
categories Analogue
components, Mixed signal
components, Digital signal components are classified
into Standard components, Semicustom
components, Custom parts
.
A) Analog components
1) Standard components
2) Semicustom components
3) Custom parts
B)
Mixed signal components
1)
Standard components
2) Semicustom components
3) Custom parts
C) Digital components
1) Standard components
2) Semicustom components
3) Custom parts
1) Standard components
First subcategory standard component this
is design and made by manufactures and users can not change function in it these are manufactured in very large
scale and made by different companies with same parameters.
2) Semicustom components
Second subcategory is semicustom
components these are configured by manufacturers but some block of memory of the I c is changeable these can be change once or unlimited times semicustom components include programmable
gate array programmable read only memory and microcontrollers.
3) Custom parts
Third subcategory is the custom parts
these can be made by using computer aided design (CAD).
A) Analog components
Now the main category Analog components
is type which consist of parameters like signals amplification oscillations etc. Common families include amplifiers, comparators, buffers, function generator etc.
B) Mixed signal components
Mixed signal components parameter are the
combination of analogue and digital parameters and made from analogue and
digital components combination.
C)
Digital components
Digital components
is type which consists of parameter like 1 or 0, high or low, plus or minus, true or false etc. common families include Transistor Transistor Logic (TTL), CMOS, MOSFET.
