What is an integrated circuit?

The English name abbreviation of the integrated circuit board is IC (integration circuit) refers to the active components (such as diodes, transistors, field effect transistors, etc.) and passive components (such as resistors, capacitors, inductors) in the circuit board. And wiring, etc., assembly in a substrate to form a complete circuit which having certain function, and then packing in a special casing. The integrated circuit has the advantages of small volume, light weight, low power consumption, good performance, high reliability, and stable circuit, and is widely used in electronic pcb products. The advent of integrated circuits is a new leap in electronic technology, which has entered the era of microelectronics, thus promoting the development of advanced technologies in various fields of science and technology.

There are many ways to classify integrated circuits. According to the integration degree, it can be divided into small-scale, medium-scale, large-scale and super large-scale integrated circuits (like SSI, MSI, LSI and VISI). The current super-large-scale integrated-circuit have hundreds of millions of components on each chip, and the chips area is only a few tens of square millimeters. According to the conductivity type, it can be divided into a bipolar integrated circuit, a unipolar integrated circuit, and a compatible integrated circuit. According to the function, it can be divided into digital integrated circuits and analog integrated circuits. Common digital integrated circuits include TTL circuits, DTL circuits, ECL circuits, and HTL circuits. Analog integrated circuits have commonly used A-D, D-A converters, operational amplifiers etc,.
