IC classification [chip decryption]
Update date：2012-7-24
From the date of birth from the IC, the IC is different from different angles I classification. According to the different manufacturing processes can be divided into semiconductor integrated circuits, thick film integrated circuits, thin-film integrated circuits and hybrid integrated circuits; function and nature can be divided into the digital IC, analog IC phase microwave integrated circuits; according to integrated The scale can be divided into small-scale, medium scale, large-scale and large scale integrated circuits.
Classified by function
(1) digital integrated circuits
Corresponds to "1" and "0" binary digital in order to "open" and "off" two states or to the high, low. And digital computing, storage, transmission and conversion integrated circuit known as a digital IC. The basic logical relationships in the digital circuit "and", "", "non-" three, and then by their logic circuits Fan between the circuit and Levin a specific persuade. Trigger counter; register and decoder. Compared to analog circuits, digital circuits in the form, the type of hinge less versatile, less precision components, widely used in digital communication systems, computer parked dynamic control plot.
Digital integrated circuits can be like divided into bipolar digital evolves into a circuit and MOS field effect transistor glanced digital IC. Bipolar digital IC suppliers 54XX, 74XX, 74LXX Series, commonly used CMOS digital integrated circuits FET 4000 and 74HCXX series.
(2) analog integrated circuits;
Analog voltage and current efficiency of large, conversion, modulation integrated circuit called analog integrated circuits. Digital integrated circuits other than the IC are collectively referred to lying analog integrated circuits for analog integrated circuits and high precision, variety, versatility is small. Analog integrated circuits can be divided into two kinds of linear integrated circuits and non-linear integrated circuits.
① linear integrated circuits
Refers to the input and output signals showed a linear relationship between the IC. Mother of many of this type of integrated circuit, functional diversity, members common to various types of op amps. Linear integrated circuits has been widely used in measuring instruments, control devices, television, radio, communication equipment, radar and other.
② non-linear integrated circuits
Non-linear IC is not a linear relationship between the output signal as the input signal changes, but do not switch the nature of the IC. Mostly non-linear integrated circuits ASIC, the input and output signals are usually analog - digital, AC - DC, high frequency - low frequency is - a mixture of negative signal, it is difficult to use a pattern to unify. The commonly used non-linear integrated circuits: for communications equipment, mixers, oscillators, detectors, frequency discriminators, in view of the phase detector for industrial measurement and control module - the number of isolation amplifiers, AC - DC converter, regulator circuit, and specifically states in a variety of household appliances in the integrated circuit.
(3) microwave integrated circuits
Work more than the 100 MHz microwave frequency integrated circuits, referred to as microwave integrated circuits. It is the use of semiconductors and thin and thick film technology, in the insulating substrate L-specific sources, passive components and microstrip transmission lines or other special micro-waveguide contact into an overall composition of the microwave circuit.
Microwave integrated circuits with small size, light weight, good performance, high reliability and low cost to the holding point, measured in the microwave, microwave terrestrial communications, navigation, radar, electronic warfare, missile guidance, and Space and other important areas has been widely used.
2) Press the integration scale classification
Integration is less than 10 gates or less small components of the integrated circuit 100, known as small-scale integrated circuits.
Integrated between 10 to 100 gates. IC or component count between 100 and 1000 referred to as medium-scale integrated circuits.
Integration in more than 100 gates or more than 1000 components, integrated circuits, known as LSI.
Integration of the integrated circuit of 10000 gates or 100 000 components. Known as the ultra-LSI.
