Researchers in UT Dallas’s Erik Jonsson School of Engineering and Computer Science invented a control method and specialized algorithms that allow power converters to be more useful in power environments requiring high levels of stability and precision, or that must manage varying levels of voltage. The University licensed the technology to Cirasys for further development and commercialization. Dr. Louis Hunt, professor emeritus of engineering, is chief scientist at Cirasys and a co-inventor of the technology with adjunct professor Dr. Robert J. Taylor (PhD’04). Dr. Dinesh Bhatia and Dr. Poras Balsara, both professors of electrical engineering, are involved in the research and development.
The integrated circuit design program at UT Dallas is turning heads: Three of the program’s papers were recently ranked among the top 50 downloads from the Institute of Electrical and Electronics Engineers.
The University’s integrated circuit design program has expanded in recent years to more than a dozen professors and several dozen graduate students in the Department of Electrical Engineering
“This says the work we’re doing is highly relevant and top-quality,” said Dr. Kenneth K. O, a professor of electrical engineering and director of the Texas Analog Center of Excellence
(TxACE) at UT Dallas. “And it’s rare that one institution has this many papers in one research area at once.”

Other members of the team are (second row, from left) graduate students Xiaojiang Tian, Jay Shah and Ali Montazeri, and (third row, from left) grad student Gaurav Sureka, undergraduate Allen Webb and grad student Liu Zhengjie. Team members not pictured are grad student Essam Atalla, former grad student Beilei Zhang and associate professor of electrical engineering Dinesh Bhatia.
The federal government has extended a contract with researchers at The University of Texas at Dallas to develop wireless communications technology that can easily skip from one standard to another, enabling ubiquitous connectivity.
The technology is being developed for emergency workers, but it’s expected to find eventual consumer applications as well.
Known as software-defined radio, the secret to the technology lies in software modules that run on an all-purpose processor. That differs from the usual approach, in which cell phones are hardwired to work with just one type of signal.
Dr. Poras Balsara, a professor and associate chair of electrical engineering in the Erik Jonsson School of Engineering and Computer Science at The University of Texas at Dallas (UTD), along with his doctoral student, Ramakrishnan Venkatasubramanian, received second place for their design paper at the joint meeting of 19th Institute of Electrical and Electronics Engineers (IEEE) International Conference on VLSI Design and 5th International Conference on Embedded Systems and Design held recently in India.
