Professor Hajimiri’s group does research on electronics and photonics integrated circuits and their applications in various disciplines, including high-frequency and high-speed communications, sensing, imaging, and bio-sensing. His research group engages in both the theoretical analysis of the problems in photonics and electronics integrated circuits and biomedical devices as well as practical implementations of new systems.
Prof. Ali Hajimiri received his B.S. degree in Electronics Engineering from the Sharif University of Technology, and M.S. and Ph.D. degrees in electrical engineering from the Stanford University.
Before joining the Faculty of Caltech, he worked at Philips Semiconductors, where he worked on a BiCMOS chipset for GSM and cellular units, at Sun Microsystems working on the UltraSPARC microprocessor’s cache RAM design methodology, and with Lucent Technologies (Bell Labs), Murray Hill, NJ, where he investigated low-phase-noise integrated oscillators. In 1998, he joined the Faculty of the California Institute of Technology, Pasadena, where he is Bren Professor of Electrical Engineering and Medical Engineering, Director of Caltech Holistic Integrated Circuit Laboratory, and co-Director of the Space-based Solar Power Project. His research interests are high-speed and high-frequency electronics and photonics integrated circuits for applications in sensors, biomedical devices, photonics, and communication systems.
Prof. Hajimiri is the author of “Analog: Inexact Science, Vibrant Art” (Early Draft pdf) a book on fundamental principles of analog circuit design and “The Design of Low Noise Oscillators” (Boston, MA: Springer). He has authored and coauthored close to 300 refereed journal and conference technical articles and has been granted more than 160 U.S. patents and has many more pending applications.
He is a Fellow of National Academy of Inventors (NAI). Prof. Hajimiri was selected to the TR35 top innovator’s list. He is also a Fellow of IEEE and has served as a Distinguished Lecturer of the IEEE Solid-State and Microwave Societies. He won the Feynman Prize for Excellence in Teaching, Caltech’s most prestigious teaching honor, as well as Caltech’s Graduate Students Council Teaching and Mentoring award. He is also three-times winner of the Associated Students of Caltech (ASCIT) Undergraduate Excellence in Teaching Award. He was the Gold medal winner of the National Physics Competition and the Bronze Medal winner of the 21st International Physics Olympiad, Groningen, Netherlands. He was a co-recipient of the IEEE Journal of Solid-State Circuits Best Paper Award, the International Solid-State Circuits Conference (ISSCC) Jack Kilby Outstanding Paper Award, a co-recipient of RFIC best paper award, a two-time co-recipient of CICC best paper award, and a three-time winner of the IBM faculty partnership award as well as National Science Foundation CAREER award and Okawa Foundation award. He co-founded Axiom Microdevices Inc., whose fully-integrated CMOS PA has shipped around 400,000,000 units, and was acquired by Skyworks Inc.
He has served on the Technical Program Committee of the International Solid-State Circuits Conference (ISSCC), as an Associate Editor of the IEEE Journal of Solid-State Circuits (JSSC), as an Associate Editor of IEEE Transactions on Circuits and Systems (TCAS): Part-II, a member of the Technical Program Committees of the International Conference on Computer Aided Design (ICCAD), Guest Editor of the IEEE Transactions on Microwave Theory and Techniques, and Guest Editorial Board of Transactions of Institute of Electronics, Information and Communication Engineers of Japan (IEICE).
