The IC Classification

IC stands for “Integrated Circuit.” An Integrated Circuit is a miniature electronic circuit consisting of semiconductor devices, passive components, and other electronic components. These components are fabricated on a small piece of semiconductor material, typically silicon. The IC classification can be listed in the following:

Based on Structure and Function
According to the function and structure, the IC can be divided into three major subcategories: analog integrated circuits, digital integrated circuits, and mixed-signal integrated circuits. Analog integrated circuits, also known as linear circuits, are used to generate, amplify, and process various analog signals (amplitude of the signals varies with time, for example, the audio signals in semiconductor radios and the magnetic tape signals in recorders and so on) where the input signal is proportional to the output signal. On the other hand, digital integrated circuits are designed to generate, amplify, and process various digital signals (signals with discrete values in both time and amplitude), such as logic control and replay of audio and video signals in devices like 3G phones, digital cameras, computer CPUs, and digital TVs.

Classification by Manufacturing Process
Integrated circuits are further classified by their manufacturing process into semiconductor integrated circuits and film integrated circuits. Film integrated circuits are divided into thick-film integrated circuits and thin-film integrated circuits.

Classification by Integration Level
Integrated circuits are categorized based on their integration level, including SSIC (Small Scale Integrated Circuits), MSIC (Medium Scale Integrated Circuits), LSIC (Large Scale Integrated Circuits), VLSIC (Very Large Scale Integrated Circuits), ULSIC (Ultra Large Scale Integrated Circuits), and GSIC (Giga Scale Integration).

Classification by Conductive Type
Integrated circuits can be classified by their conductive type as bipolar integrated circuits and unipolar integrated circuits, both falling under the category of digital integrated circuits. Bipolar integrated circuits have complex manufacturing processes and higher power consumption, including types like TTL, ECL, HTL, LST-TL, STTL, etc. Unipolar integrated circuits have a simpler manufacturing process, lower power consumption, and are easily scaled up. Representative types include NMOS, PMOS, CMOS, etc.

Classification by Application
Integrated circuits are classified based on their application in TVs, DVD players, video recorders, electronic keyboards, communication devices, remote controls, language devices, and alarm systems.TV circuits include line and field scanning circuits, mid-frequency circuits, audio circuits, color decoding circuits, AV/TV conversion circuits, remote control circuits, audio decoding circuits, picture-in-picture processing circuits, microprocessor circuits, and memory circuits. Audio circuits for sound systems include AM/FM high-frequency circuits, stereo decoding circuits, audio preamplification circuits, audio operational amplifier circuits, surround sound processing circuits, level driving circuits, electronic volume control circuits, delayed reverberation circuits, and electronic switch circuits.DVD player circuits comprise system control circuits, MPEG decoding circuits, audio signal processing circuits, video encoding circuits, RF signal processing circuits, digital signal processing circuits, and motor drive circuits. Video recorder circuits consist of system control circuits, servo circuits, audio processing circuits, and video processing circuits.

Classification by Application Fields
Integrated circuits are classified by their application fields into standard general-purpose integrated circuits and special-purpose integrated circuits.

Classification by Package:
Integrated circuits are categorized by their package types into dual in-line integrated circuits and surface mount integrated circuits. Dual in-line integrated circuits are further divided into dual-row (double-row pin) integrated circuits and single-row (single-row pin) integrated circuits. Small-power dual in-line integrated circuits are often made with the dual-row leads, while high-power integrated circuits are mostly produced with the single-row leads. Surface mount integrated circuits are further divided into double-row surface mount and quad surface mount types. Medium and small-scale surface-mount integrated circuits are often welded via double-row pads while large-scale surface-mount integrated circuits are mostly soldered via quad pads.
