With the continuous reduction of circuit power supply voltage, low voltage operational amplifier design is becoming a research hotspot. According to Zhang Zhicai, Juxun low-voltage low-power operational amplifier chips include single channel GS6001, dual channel GS6002, four channel GS6004, etc., which can be used in sensor interfaces, smoke detectors, medical instruments and portable systems. Among them, the minimum operating voltage of GS6001 can be as low as 1.8V. This new rail to rail low-voltage operational amplifier has a great competitive advantage over its peers in terms of cost, and can be used in applications such as Internet of Things sensing devices, portable instruments and meters, smart homes, etc.
It is worth mentioning that with the technical breakthrough and application innovation in IC design, the product "Low voltage and low power consumption operational amplifier GS6001" of Juxun Semiconductor won the ASPENCORE "2021 China IC Design Achievement Award" annual best amplifier/data converter, which fully demonstrates the high recognition of Juxun products by customers and the market.
In addition, in terms of low-voltage and low-noise operational amplifiers, the GS8634 product of Juxun Semiconductor has entered the intelligent controller supply chain system of No. 9 Company‘s two wheeled vehicles by virtue of its excellent performance. It is understood that the GS8634 has a 6MHz high gain bandwidth product, 4.2V/ μ S conversion rate, 13nV/√ Hz noise. Among them, high bandwidth gain and low noise can ensure the accuracy of current detection to ensure the normal operation of the whole system and provide high-quality performance.
The signal chain chip ushers in the golden age of domestic substitution, and Juxun Semiconductor can benchmark many of the same type of operational amplifier products of Texas Instruments
It is well known in the industry that analog chips refer to chips that process continuous physical quantities such as light, sound, electricity/magnetism and natural analog signals such as temperature. They are mainly composed of power management chips and signal chain chips according to product types. Among them, the signal chain chip refers to the integrated circuit that has the ability to transmit, transmit, convert, amplify and filter analog signals, accounting for about 47% of analog chips.
Benefiting from a longer life cycle and more decentralized application scenarios, the market of signal chain analog chips has enjoyed a good development trend in recent years, and the industry scale has grown steadily. According to WSTS data, the global signal chain chip sales will be about 34.829 billion dollars in 2021, and it is expected to grow to 45.175 billion dollars by 2023. China is the world‘s major signal chain chip market, with the market scale accounting for about 1/3 of the global market.
From the perspective of the competition pattern, the market share of the global signal chain chip is roughly the same as that of analog chips. Texas Instruments, Adelaide Nuovo, Scarlett, Infineon, Italy France Semiconductor, NXP, Maxine, Anson, Microchip and Renesa Electronics together account for about 63% of the market share of the global market. Among them, Texas Instruments, as the leading enterprise in the industry, has more than 80000 products, accounting for 19% of the global market share, and is the absolute leading enterprise in the field of signal chain and even analog chips.

In terms of domestic market, signal chain chip manufacturers mainly include Simbond, SRIPP, Huiding Technology, Xinhai Technology, etc. At present, domestic products are still in the low-end field, mainly in the field of amplifiers, comparators, and interface chips. The product homogeneity is serious, and there is less involvement in high-end ADC, high-frequency devices, base station signal link chips and other fields. In addition, domestic factories are small in commodity category and scale, lacking the ability of overall serialization solutions.
Zhang Zhicai pointed out that: "From the perspective of the industrial chain, as the local enterprises have long been positioned at the downstream of the signal chain chip, there is still a huge gap between the domestic manufacturers and the signal chain chip giants, such as Dezhou Instruments, Adeno and other international manufacturers. Juxun Semiconductor has a relatively complete range of products in the signal chain field, and its technical level is at the leading domestic level. It is one of the few domestic companies that can directly compete with global well-known companies in the same industry, and has broken through overseas technologies in key areas Technology monopoly. "
The Bugs on Chip reporter noticed that although China‘s signal chain chip market has accounted for 1/3 of the global market, the self-sufficiency rate is only about 12%, and there is a huge gap between the production and manufacturing of chips and their own consumption. In addition, due to the highly decentralized characteristics of the signal chain chip market, one or two companies cannot achieve full monopoly. Even if it is as powerful as Texas Instruments, its market share will be only 19% in 2021, which undoubtedly provides a favorable development opportunity for Chinese manufacturers.
With the increase of domestic substitution demand, with the support of policies and capital, China‘s signal chain chip enterprises have entered the golden period of development, and relevant products have been continuously verified and introduced by downstream key customers.
"There are many kinds of signal chain chips, and each segment has a dominant position. For example, Texas Instruments has the first market share in the amplifier market, but Infineon has a large advantage in the power chip market. On the whole, there is no single enterprise that has a dominant position in all signal chain segment markets, so there is still a lot of development opportunities for domestic alternatives to the segment track. At present, our amplifier products can benchmark Texas Similar models of instruments can be compared with them in terms of performance and power consumption, while they can be made cheaper. " Zhang Zhicai emphasized.
Compared with the IDM model adopted by international giants, the Fabless model does not need to invest too much capital in building plants and purchasing equipment. Therefore, domestic signal chain chip manufacturers are expected to accelerate their development by continuously increasing R&D investment and asset light Fabless model, and gradually narrow the gap with international leading manufacturers.
"At present, we use TSMC‘s wafer foundry and Changdian Technology‘s packaging test to ensure the advancement of the company‘s product process technology and packaging technology." Zhang Zhicai said, "In terms of sales network, the company‘s distribution channel has a dual approach online and offline, and Juxun Semiconductor products are available in Huaqiang Mall (www.hqbuy. com) and other channels."

Both parties are speeding up the pace of research and development of car gauge level simulation products. At present, many car gauge chips are under AEC-Q100 certification. In the future, Juxun will join hands with Jujie Electronics to speed up product research and development, and integrate internal resources in the automotive electronics, industrial and energy storage markets to provide customers with battery pack sensing, tire pressure monitoring, signal conditioning, wireless sensing, wireless communication, and power management , signal chain products and other overall solutions, as well as full life cycle support and services, strive to become the leader in the domestic semiconductor industry. "
epilogue
Compared with digital chips, analog chips have the characteristics of complicated application fields, long life cycle, long personnel training time, low price but stable, and closer coordination with the manufacturing process. Based on these characteristics, products, customers and talents need to simulate the long-term accumulation of enterprises, which is the main source of their long-term competitive advantages.
Since its establishment, Juxun Semiconductor has always adhered to the continuous innovation of technology and products, and constantly increased R&D investment to expand product categories and iterative upgrading to meet various needs of analog chips in various downstream market segments. It is believed that the company will further improve the competitiveness of its products in the market to achieve steady growth in scale and profits after cooperating with Yujie Electronics.
