A few days ago, sponsored by the ewei - the fifth China ICT media BBS held in shenzhen, many leading international semiconductor companies technical experts, Shared the 2016 technology development trend of semiconductor industry. The author was invited to participate in the BBS
Qorvo: RF front-end integration is a trend
Qorvo mobile product market strategy manager tao said in his speech, the Asia Pacific region, from 4 g to 4 g + to future 5 g rf front end will constantly integration.
"We have all of the rf front-end process and all product types, so in the future 5 g smartphones and 4 g + smart phones, we believe that the integrated scheme is a market trend," tao said. "This year, commercial or two carrier carrier aggregation, over the next year or the year after may have three carrier four carrier even five carrier, the carrier number, the more can provide faster rate of ascending and descending."
Tao also predict that the earliest in the world, with 5 g may be South Korea or Japan. South Korea has the winter Olympics in 2018, Japan has a summer games in 2020. The two is the most important event for the local government, local operators to do 5 g demonstrate the best platform. So we see that in 2018, the south Korean Olympic spectrum is currently with the display of 28 g spectrum. In 2020 Japan's summer games could adopt or less than 6 g do wide area coverage, high frequency is mainly used for hot spot coverage.
Cypress: sensors require energy collection technique
Sensors on the application of Internet of things is indispensable, but a lot of sensor application scenario for the often not too often suited to change batteries, not convenient to replace the battery. Energy collection technique, therefore, in the future of the Internet of things applications, will play a very important role.
In August last year, Cypress came to a new energy S6AE101A collection chip, and a global minimum, the minimum power consumption of wireless sensor, using solar-powered wireless sensor module.
This module has three characteristics: it is low power consumption, current is only 250 nA; Second, working current is only 250 nA, the global minimum one; Three is a very high level of integration, don't need any power supply chip, periphery on a fix. So you can use a square centimeter of the solar panel can make the whole system works.
Fujitsu: 2016 will be gallium nitride is very important for a year
Survey data show that in 2020 a gallium nitride is expected to obtain the compound annual growth rate of 100%. This unique semiconductor receiving increasingly widely used in power, the device, it has more than silicon reverse charge lower and lower recovery time, with these outstanding features, gallium nitride device is fill the blank of the power supply design development roadmap, which play a higher efficiency in emerging applications.
Several companies are now concerned with gallium nitride, include in Taiwan and some domestic power supply manufacturers, also includes huawei has slowly made with gallium nitride product, this will be a gallium nitride is very important for a year. Fujitsu, estimated in 2016 as the gallium nitride production slowly lower price, they can achieve 1.2 times to 1.2 times the traditional this price.
ADI is the earliest in MEMS research and development of the company, in 1987, has put in MEMS research and development. In 2002 released the first iMEMS products. In 2011, ADI has released its first to support the MEMS sensor is of high temperature to 175 degrees, until January 2016, ADI is currently the only one able to support 175 degrees high temperature sensor manufacturers. Company also invented the millet hand ring inside of the application of MEMS products, the three or four years, the industry is still the lowest power consumption.
Micro-electro-mechanical product and application manager of ADI asia-pacific Zhao Yanhui that ADI can win market share mainly has three points: the first is the power consumption; The second is accuracy; The third is the size.
Power Integration: safety is the biggest challenge of quick charge mass production
Power Integration company, founded in 1988, mainly engaged in high voltage control circuit of the integrated chip suppliers, its products mainly include quick charger, AC - DC Power supply used some of the fields.
At present, including mediatek, qualcomm, many manufacturers have introduced a fast charging technology, especially qualcomm Quick Charge 3.0 Quick Charge agreement, is among the best. But these techniques for quick charger manufacturers, there are a lot of challenges. Include a very high power density, on the premise of output voltage variable still can meet the specification requirements of the transformer design efficiency, and of different protocols
Power Integration launched a series of InnoSwitch switching Power IC, including high pressure quick charge InnoSwitch CH series and the auxiliary and InnoSwitch EP series of standby Power supply for smartphones InnoSwitch CP series products in the field of quick charge. In addition, in the applications of fast charging Power Integration also provides can satisfy both qualcomm QC2.0 and QC3.0 protocol interface IC products.
This solution can be found in different input voltage, load, temperature and mass production conditions, the output can meet 3% of the voltage regulation accuracy, and can meet the requirements of all laws and regulations on efficiency of energy efficiency. In addition, the InnoSwitch - CP IC also has a set of perfect advanced protection function, including: over voltage protection; Reduced to 3 v output when the automatic restart over-current protection; Has the hysteresis characteristics of the heat off protection and with precise input threshold voltage rise slowly/slow drop input overvoltage protection features. And this series IC crossover between the primary and the secondary side, through the global safety certification agencies and a number of qualified certification, can be in line with the global different safety standards.
