Integrated circuit is a kind of micro electronic device that uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components needed in a circuit. Today, Follow YFM to learn more about the functions and classification of integrated circuits.

Classification of integrated circuits

1.according to the application field

Integrated circuit can be divided into standard general purpose integrated circuit and ASIC according to the application field.

2.according to the appearance

Integrated circuits can be divided into circular (metal shell transistor package type, generally suitable for high power), flat type (good stability, small size) and double in-line type.

3.according to the production process

Integrated circuit can be divided into semiconductor integrated circuit and thin film integrated circuit according to the manufacturing process. Membrane integrated circuits are classified into thick film integrated circuits and thin film integrated circuits.

4.according to the integration of high low score

According to the degree of integration, integrated circuits can be divided into small-scale integrated circuits, medium-scale integrated circuits, large-scale integrated circuits, VLSI, VLSI and VLSI.

5.according to different types of conductivity

Integrated circuit can be divided into bipolar integrated circuit and unipolar integrated circuit according to the conductive type, they are digital integrated circuit. Bipolar IC has complex manufacturing process and high power consumption, and there    are TTL, ECL, HTL, LST-TL, STTL and other types of representative IC. The fabrication process of unipolar integrated circuit is simple, and the power consumption is also low. It is easy to make large-scale integrated circuit, and the representative    integrated circuit includes CMOS, NMOS, PMOS and other types.

6.according to the functional structure

Integrated circuit according to its function, the different structure, can be divided into analog integrated circuit, digital integrated circuit and digital/mode hybrid integrated circuit three categories. Analog integrated circuits, also known as linear    circuits, are used to generate, amplify and process a variety of analog signals (signals whose amplitude varies over time). For example, the audio signal of a semiconductor radio, the tape signal of a video recorder, etc.), whose input signal is proportional    to the output signal. Digital integrated circuits are used to generate, amplify and process various digital signals (signals with discrete values in time and amplitude). For example, VCD, DVD playback audio signals and video signals).

the role of integrated circuits

1. Reduce the use of components. The birth of integrated circuit, small-scale integrated circuit to reduce the number of content components, in scattered components have a great technical improvement.

2. Product performance has been effectively improved. The components are gathered together, not only reduce the interference of external electrical signals, but also have a great improvement in circuit design, improve the speed of operation.

3. more convenient application. A kind of function corresponds to a kind of circuit, a kind of function is concentrated into an integrated circuit, so that - in the future application, what function can be applied to the corresponding integrated circuit,    which greatly facilitates the application.

The above is Yufan micro engineers for the role of integrated circuit and classification of all content to share, I hope to bring help to you.
