What is digital corePieces of? Analysis of the development prospect of digital chip Industry

Chip technology is one of the key infrastructures of the modern digital society and plays an important role in the development of various industries. The following are some aspects of the chip technology development prospects: Artificial intelligence and machine learning: With the popularity and application of artificial intelligence and machine learning, the demand for high-performance chips is increasing.

The upstream of the chip industry chain is the EDA industry, and it is also the highest end of the entire industry chain. EDA software is the mother of chip and the necessary software tool for chip design. At present, the global chip design of high-end software EDA isThe signal.

2, analog chip and digital chip are two different types of integrated circuits, they have some significant differences in function and application: analog chip: analog chip processing continuous signals, such as sound, light, etc., they can amplify, filter, modulation and other operations on the signal. The output of the analog chip is continuously changing and can represent an infinite number of values. Analog chips are often used in applications such as sensors, amplifiers, and filters where continuous signals need to be processed.

3, the main difference between digital chips and analog chips is the way they process and transmit signals. Digital chips process discrete numbersWord signals, while analog chips process continuously changing analog signals. First, digital chips, as the name suggests, are specifically designed to process digital signals. Digital signals have only two states: high and low, which usually correspond to the 1s and 0s of binary numbers.

RF chips, why is it known as the "pearl in the crown of analog chips"?

1, the RF chip belongs to a kind of analog chip (CPU, GPU, etc., belong to the digital chip), known as the pearl in the crown of the analog chip, visible research and developmentIt is indeed difficult, but it is not as difficult as CPU and GPU, and the latter two are several orders of magnitude more than RF chips. In this regard, Huawei has given a very good answer, and I will do a detailed analysis later. In 2017n, the domestic RF chip market share is only 2%. 2, RF chip, simple understanding, is a key component connecting the mobile phone baseband and the mobile phone antenna, mainly responsible for the transmission and reception of wireless information, including: filter, power amplifier, RF switch, low noise amplifier and other important components, known as the "analog chip crown pearl". Expected this year, Qualcomm RFChip revenue may reach 8% of total revenue and will continue to grow in the future.

3, RF chip RF chip refers to the radio signal communication into a certain radio signal waveform, and through the antenna resonance sent out an electronic component, as one of the important parts of 5G, RF chip in the development of 5G occupies a pivotal role, known as analog chip "crown pearl".

4, the RF chip is the pearl in the crown of the analog chip, and the analog chip has always been China's weakness.

5, in fact, the 5G chip alone isThose who cannot use 5G networks also need key technology, that is, 5G radio frequency chips. The chips are used in mobile phones to send and receive data, but 80 percent of them are owned by the United States and Japan. So China can't develop this technology? Rf chips require in-depth research in terms of equipment architecture, manpower, patents, etc., especially in terms of patents, which is still quite difficult for our country.

6, if the use is vivo mobile phone, mobile phone RF refers to the function module that receives and sends mobile phone signals.

Power management chip or digital chip which is better

1, in simple terms, such as everyone's familiar MCU and large computing chip SOC, are digital chips. They are the "network red" in the chip, which has attracted the attention of the technology circle and the capital market, and the names of Nvidia, Qualcomm and Horizon can be seen everywhere on social media. In the car, the number and variety are more, more work is done, and the design threshold is higher, and it is classified as analog chips.

2, in addition from the current industry situation, the power management IC design talent, than the digital IC lack, and power ICA greater range of knowledge and experience is required. It is worth mentioning that digital power chip products, the product has been the focus of the industry in the past two years, but it is not popular, marketing applications have not achieved rapid development, and from the current point of view, digital power in the past year or two is still difficult to have a big breakthrough.

3, because these two chips are the two essential chips in the circuit. The charging chip is responsible for converting electrical energy into electric charge to charge the device. Different types of charging chips have different functions, such as controlling the charging rate and protecting the device from overcharge, overdischarge, short circuit and other damage. Power sourceThe management chip is responsible for controlling the power supply and voltage, current and other parameters of the entire charging circuit.

4, the power management chip is a chip used to manage the power supply, which can realize the power switch, regulation, monitoring and other functions. Hunter Core offers various types of power management chips.

5, however, the output pulsation and switching noise of this type of power controller are relatively high and the cost is relatively high. If the input voltage and output voltage are very close, it is best to choose the LDO regulator, which can achieve high efficiency and, most importantly, low cost.
