What is the role of IC?

IC refers to IC chip.

IC chip (integrated circuit chip) is an integrated circuit formed by a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic base to make a chip. IC chips include wafer chips and packaging chips, and the corresponding IC chip production line consists of two parts: wafer production line and packaging production line.

Integrated circuit (integrated circuit) is a kind of miniature electronic device or component, using a certain process, the transistor, diode, resistor, capacitor and inductor and other components and wiring required in a circuit are interconnected together, made on a small piece or several small pieces of semiconductor wafer or dielectric substrate, and then encapsulated in a tube shell to become a miniature structure with the required circuit function; All of these components have been structurally integrated into a single unit, making electronic components a big step towards miniaturization, low power consumption and high reliability. It is denoted by the letters "IC" in the circuit.

The IC major is the integrated circuit design major.

Integrated circuit design is a discipline of electronic engineering and computer engineering, and its main content is to design integrated circuits (ICs) using professional logic and circuit design techniques.

IC design involves expertise in both hardware and software. Integrated circuit design involves the creation of models of electronic devices (e.g., transistors, resistors, capacitors, etc.) and interconnects between devices. All devices and interconnects are housed on a single semiconductor substrate material, and these components are housed on a single silicon substrate through semiconductor device manufacturing processes (e.g., photolithography, etc.) to form circuits.

Classification

1. IC layout designer.

The main responsibility of the IC layout designer is to design and verify the layout of the back-end of the integrated circuit through the EDA design tool, and finally generate the GDSII data for integrated circuit manufacturing. Layout designers often need to communicate and collaborate with digital design engineers and analog design engineers at all times to get the job done.

An excellent layout designer must not only have the ability to design and understand circuits, but also have excellent process knowledge.

2. Simulation design engineer.

As a key person in the design process, the job of the analog design engineer is to complete the circuit design of the chip. Due to the different design platforms adopted by various design companies, and the requirements for circuit design of different materials and products are also very different, the core skills of analog design engineers are to have the circuit design knowledge and experience required by enterprises, and have rich theoretical knowledge of analog circuits.

At the same time, it is also necessary to guide the layout design engineer to realize the layout design of the analog circuit.

1. Operation function, this function completes the user's control operation of the TV such as program preselection, volume, brightness, contrast, and chromaticity.

2. Adjustment function, this function mainly completes the function of setting up and adjusting the working mode of each unit circuit of the TV. When entering the industry mode, we can use the remote control or operation key to complete the adjustment of high amplification AGC, sub brightness, sub contrast, sub volume, field width, field linearity, field center, row width, pillow calibration, white balance, etc.

3. The detection shows that the CPU can scan and detect the connected IC through the IC bus, and display the faulty IC on the screen.

4. The automatic adjustment function, that is, the so-called automatic data recovery function, is required when the memory is to be replaced.

Power supply IC refers to the pulse width control integration of switching power supply, and the power supply relies on it to adjust the stability of output voltage and current.

Developmental classification. With the development of electronic technology, especially the current popularity of portable products and the promotion of energy conservation and environmental protection, power ICs play an increasingly important role. A few years ago, power ICs were just integrated regulators and DC converters, but now electronic ICs

It covers a wide range of topics, including DC DC, LDO (Low Dropout Line Regulator), battery charge and discharge management, PWM controllers, RESET, PFC (Power Factor Correction), energy saving control, power MOSEFT, and more.

ICs are called integrated circuits. A circuit that integrates a variety of functions. Different ICs have different functions (functions).

IC (Integrated Circuits) integrated circuits.

It is the use of semiconductor process or thin and thick film process (or a combination of these processes) to make the active components, passive components and interconnection wiring of the circuit together on the semiconductor or insulating substrate to form a closely connected overall circuit in the structure.

Compared with discrete bulk circuits, integrated circuits greatly reduce the size, weight, number of leadouts and solder points, improve circuit performance and reliability, while reducing costs and facilitating mass production. From discrete components to integrated circuits, it is a leap forward in the development of semiconductor electronic technology. Classification of ICs:

IC can be divided into digital IC, analog IC, microwave IC and other ICs according to their functions, among which, digital IC is the most widely used and fastest-growing IC variety in recent years. Digital IC is an IC that transmits, processes, and processes digital signals, and can be divided into general-purpose digital IC and special-purpose digital IC.

General-purpose ICs: Refers to those standard circuits with many users and a wide range of applications, such as memory (DRAM), microprocessors (MPUs) and microcontrollers (MCUs), etc., which reflect the current status and level of digital ICs.

Specialized ICs (ASICs) are circuits designed for a specific user or a specific purpose.

Does this still need to be asked! The CPU is an IC, the graphics card is an IC, and the memory is an IC, and you can't use a computer without an IC.

Now the range of IC is wider, it can be said that without IC, most of the electronic products you see will not work, including your computer, toys, mobile phones, radios, televisions, etc.

ICCI full name in Chinese: International Chamber of Commerce Internet.

English name of Token: Internet Chamber of Commerce International

The International Chamber of Commerce (ICC) is a powerful force for peace and prosperity, and promotes an open international, investment system and market economy. Since the member companies and associations of the ICC are themselves engaged in international business activities, it formulates regulations that regulate international business cooperation.

For example, the Uniform Rules for Collection, the Uniform Customs and Practice for Documentary Credits, and the 2010 International Principles of Interpretation of International Terminology have been widely used in the international Convention and have become an indispensable part of the world, and the International Court of Arbitration under the International Chamber of Commerce is the highest arbitration institution in the world, which plays a significant role in resolving international disputes.
