PhD Liang Rong
CONGRATULATIONS ON YOUR GRADUATION
Liang Rong received his master degree at School of Information- and Communication Technology in 2006. A year later in 2007 he came back to Kista for doctoral studies and now he has defended his PhD Thesis "All Digital Polar Transmitter Design for Software Defined Radio - Architecture and Low Power Circuit Implementations"
Where are you from and where did you study before coming to KTH-ICT?
– I graduated from Shanghai Jiao Tong University China in 2003 with B.EE degree and came to study in the ICT/ECS as international master student in 2004. During that time, I was in the SoC program provided by KTH. I graduated in 2006 with M.Sc in EE specialized in SoC design in 2006 and then I went back Shanghai and worked in a silicon design foundry. In year 2007 I was accepted as Ph.D. by iPack Center in ICT/ES and began my journey towards doctoral degree. I feel happy that it is done this year.
What is your topic and why did you choose it?
– My initial topic is "Low Power Circuit and System Architecture Exploration in Nano-Meter RF CMOS Technology" and the final title of my thesis is "All Digital Polar Transmitter Design for Software Defined Radio -- Architecture and Low Power Circuit Implementation". I chose this topic because firstly, I have related background in the cross region of wireless-radio architecture and SoC system design, I also have the experience from the industry (2 career period 2003-2004 and 2006-2007) in the silicon design and manufacture. Secondly, I am interested in the hardware design and hope to do something from the beginning to the end. That is the way from most basic chips to the final creative, useful design for people's daily life.
Describe your topic in short
– In short, OK, I am designing silicon chips with innovative low power circuit architecture so that everyone can use the design in daily wireless connection with minimal cost. It is also very power efficient and green to the environment as well.
Tell us something about your results
– The result is very inspiring not only from academic aspect but also from industry aspect. With the co-work and cooperation with industry, the work has been published in the TOP journal of the IEEE Solid-State Circuit Society (JSSCC) and there are very few ones in our department/school, it increase the fame of our department/group and make us more competitive with equivalent department in Lund or Linkoping or Uppsala university. From industry aspect, the work investigated and opened a new design methods for future wireless communication system which leads to many interesting applications, they will facilitate the daily life and can be implemented in RFID or other wireless communication systems.
What will the future bring for your research topic?
– The research project reveals a new possibility for silicon design in the wireless communication area and this may greatly reduce the manufacture cost for application of RFID or WLAN/4G. So people's wireless connection with others will be more low cost not only financially but also green in the power consumption area.
What are your future plans?
– I am currently looking for funds and I also applied European projects to carry on the first demo of the system. Also I am seeking Sweden local telecom giants for cooperation possibility. I hope I can find a good job position in this area and do something that may have commercial value. I have been staying here for almost 7 years and Stockholm is almost my second hometown now. It is a great pity for me that my Swedish is not progressing so much.
