  IC Functional structure

Integrated circuits, also known as IC, according to its function, the structure of different, can be divided into analog integrated circuits, digital integrated circuits and digital / analog hybrid integrated circuits three categories.

Analog integrated circuits, also known as linear circuits, are used to generate, amplify and process various analog signals (ie, amplitude-varying signals such as audio signals from a semiconductor radio, tape recorder, etc.) whose input and output signals are ratio. Digital integrated circuits are used to generate, amplify and process various digital signals (ie, signals that are discrete in time and amplitude, such as 3G handsets, digital cameras, computer CPUs, logical controls for digital television, and replayed audio signals And video signals).

Craftsmanship

Integrated circuit according to the production process can be divided into semiconductor integrated circuits and film integrated circuits.

Membrane integrated circuits also classify thick film integrated circuits and thin film integrated circuits.

IC Integration level

Integrated circuit by the level of integration can be divided into:

SSIC Small Scale Integrated circuits (Small Scale Integrated circuits)

MSIC medium scale integrated circuits (Medium Scale Integrated circuits)

LSIC large scale integrated circuits (Large Scale Integrated circuits)

VLSIC Very Large Scale Integrated circuits (Very Large Scale Integrated circuits)

ULSIC Ultra Large Scale Integrated circuits (Ultra Large Scale Integrated circuits)

GSIC's large scale integrated circuits are also known as very large scale integrated circuits or ultra-large scale integrated circuits (Giga Scale Integration).

Conductive types are different

Integrated circuit according to the type of conductivity can be divided into bipolar integrated circuits and unipolar integrated circuits, they are digital integrated circuits.

Bipolar integrated circuit manufacturing process is complex, large power consumption, on behalf of the integrated circuit TTL, ECL, HTL, LST-TL, STTL and other types. Unipolar integrated circuit production process is simple, low power consumption, easy to make large-scale integrated circuits, on behalf of the integrated circuit CMOS, NMOS, PMOS and other types.

By use

The integrated circuit can be divided into integrated circuits for use in integrated circuits such as televisions, integrated circuits for audio systems, integrated circuits for video players, integrated circuits for video recorders, integrated circuits for computers (microcomputers), integrated circuits for electronic puppets, integrated circuits for communications, and integrated use of cameras Circuit, remote control integrated circuits, language integrated circuits, alarm with integrated circuits and a variety of ASICs.
