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.
