Integrated circuit (integrated circuit, referred to as integrated circuit by Hong Kong and Taiwan) is a kind of miniature electronic device or component. A certain process is used to interconnect the transistors, diodes, resistors, capacitors, and inductors and other components and wiring required in a circuit, fabricate them on a small or several small semiconductor wafers or dielectric substrates, and then encapsulate them in a tube Inside the case, it becomes a miniature structure with the required circuit functions; all of the components have been structured as a whole, so that the electronic components have taken a big step towards miniaturization, low power consumption and high reliability. It is represented by the letter "ic" in the circuit (also with the text symbol "n", etc.).

c integrated circuit characteristics

Integrated circuits have the advantages of small size, light weight, few lead wires and soldering points, long life, high reliability, and good performance. At the same time, they have low cost and are convenient for mass production. The use of integrated circuits to assemble electronic equipment can increase the assembly density by tens to thousands of times compared with transistors, and the stable working time of the equipment can also be greatly improved.

ic integrated circuit application

IC integrated circuits are not only widely used in industrial and civilian electronic equipment such as radio cassette recorders, televisions, computers, etc., but also in military, communications, and remote control.

ic integrated circuit classification

1. Integrated circuits can be divided into three categories: analog integrated circuits, digital integrated circuits and digital/analog hybrid integrated circuits according to their functions and structures.

Analog integrated circuits, also known as linear circuits, are used to generate, amplify, and process various analog signals (signals whose amplitude changes with time boundaries. For example, audio signals of semiconductor radios, tape signals of VCRs, etc.), their input signals and output signals Proportional relationship.

Digital integrated circuits are used to generate, amplify and process various digital signals (referring to signals with discrete values in time and amplitude. For example, audio signals and video signals reproduced by vcd and dvd).
