During the 7 years of returning to China, Tian Hao undertook a major national special project, a special R&D project in Shanghai, and a lot of cooperation with related companies. He invented it. There are 2 patent authorizations, about 12 copyright protection authorizations, and 6 filed patent applications. 64 papers were published in international academic journals and academic conferences, of which 30 were first authors; 1 was co-authored. Repeatedly served as Chairman of the RF IC Branch of major international conferences such as APMC or as an invited report.
However, winning awards and patents is not Tianruo's main purpose. In his words: 'I value the transformation of the achievements of scientific research. It benefits society and people. It is the highest honor that gives me a sense of achievement!'
Do not dare to challenge breakthrough bottlenecks in research
In view of the immense market potential of the Internet of Things and the country’s development strategy, developed countries such as Europe and the United States have monopolized the node circuit market and technical standards from the very beginning. Tian Yu is eager to break this technical barrier and returned to China in 2010. The 'very low power consumption and energy-efficient wireless node chip technology platform' project for the Internet of Things is determined to complete our country's shortcomings in this field and strive to surpass the level of foreign countries and move toward the technological frontier.
However, the road to scientific research has not always been flat. Whenever it comes to setbacks, Tian Hao broke through one research bottleneck with patience and confidence.
At present, Tian Hao’s scientific research work aims at the research and development of low-power, high-energy-efficiency IoT universal and dedicated wireless node common core technologies, and studies common and specialized chip design and implementation technologies that can be used for various Internet of Things applications, and establishes cores. Subsystems, sensor/node interface technologies, support systems and application development technologies, provide theoretical and technical support for research and design and application of very low power and high energy efficiency IoT wireless nodes. Based on this, further efforts are made to summarize relevant research results. For the Green Tooth technology system, it has obtained the national patent authorization, designed the relevant wireless transceiver chip, and realized the core technology chip carrier, which has been widely recognized and welcomed by the industry.
On the other hand, Tian Yu is more interested in the silicon-based millimeter wave. Tian Yu introduced: 'With the demand for low-cost high-performance systems, the development of silicon-based millimeter-wave integrated chips will become an industry. He was keenly aware of the research value of silicon-based millimeter waves. He started the preliminary research work between 2008 and 2009. After returning home in 2010, Tian Hao led the task force to continue research and has made breakthrough progress. Based on rigorous basic technology research such as silicon substrate millimeter-wave device modeling, low-resistance substrate effect suppression, and on-chip noise suppression technology, the research team used a 65-nm Si CMOS research design and 35 GHz with independent intellectual property rights. Single-chip millimeter-wave radar sensor chip is successfully taped. This chip adopts frequency-modulated continuous wave (FMCW) system, including 35GHz FMCW signal source on chip, transceiver link, power management circuit, SPI control data port, in-line calibration and IF amplifier circuit. All millimeter-wave signal processing modules, etc., can greatly enhance the integration of the new generation of millimeter-wave radar systems, and fully improve the performance of millimeter-wave systems. , The next-generation highly integrated millimeter wave radar system is significantly reduced system cost and technical practical threshold.
Stepping through the conversion channel
In the process of industrialization, Tian Hao has his own ideas. He believes that industrialization needs to be considered from the very beginning and it is a key step in the entire R&D system.
More than ten years of scientific research experience in Singapore and Denmark have provided him with a profound understanding of the industrialization of foreign scientific research achievements. After years of unremitting efforts, from the comprehensive comparison of research results published in the international field at the same time, Tian Hao The research on silicon-based millimeter-wave is at the leading position of the international first-tier echelon. With the financial support of the industry, the 35GHz single-chip millimeter-wave radar sensor chip developed by the research group is the first chip with complete functions and mass production. It is reported that this type of chip was previously completely dependent on imports and the price is very expensive. This research result has undoubtedly changed the status quo of China's silicon-based millimeter-wave chip technology lagging behind that of advanced countries in the developed world for a long time. Tian Hao has shown an example of the image, he said. This is equivalent to turning a professional SLR camera into a point-and-shoot camera, which not only drastically reduces production costs, but also saves a lot of foreign exchange for the country.
Currently, the research group is pushing research work to 77GHz and 94GHz single-chip radar sensors and 5G communication system front-end chips under the financial support of relevant companies, with a view to realizing industrialization at an early date and filling the gaps in the field in China.
Concentrate on teamwork
Tian Hao’s research career was guided by his instructor, Professor Luo Jinsheng, with the help of Professor Lin Jinting and Professor Chen Tangsheng of Nanjing Electronic Devices Research Institute. Tian Hao took the mentor’s words, deeds and enthusiasm and gave the team new strength and ambitiousness. The goal.
Tian Yu’s team is mostly composed of his master’s and doctoral students, as well as part of the staff. He set an example, and made specific demands on his team members. He believes that the scientific researcher must be determined to sit for ten years. Perseverance and perseverance do basic research in a down-to-earth manner. In addition, for an integrated circuit practitioner, both innovation and application are extremely important. We must pay attention to the basic theory research, and we must consider all aspects of achievement transformation. To carry out various scientific research work.
Under the guidance of Tian Hao, the team has always maintained the development momentum in the field of silicon-based millimeter waves for the purpose of improving China's technological level. Tian Hao said that in the future there will be more challenges and opportunities. He will fight with the team side by side. We will strive for greater industrial investment and national project support, expand R&D teams, improve testing conditions, and create R&D to mass production bases to accelerate and lead the research of silicon-based millimeter-wave integrated circuit technology. At the same time, they Jiangsu Weiyuan Microsystem Technology Co., Ltd. cooperated to establish consensus and association with the industry to obtain funding and resources support from the industrial sector in the early stage of research, and to realize the industrialization experience in the early stage of research, and explore a path of technology industrialization suited to China's national conditions. Tian Hao hopes to continue cooperation with Jiangsu Weiyuan Microsystem Technology Co., Ltd. in the next ten years to push the domestic level of technology and industrialization to a new height and promote the further development of China's industry.
