Today's silicon transistors have evolved rapidly from their ancestors to
be faster, smaller and more numerous, while the die-area of the typical
chips housing them has been constantly increasing. However, this has
come at the cost of substantial degradations in voltage handling and
matching properties due to fundamental considerations. The cut-off
wavelengths of integrated silicon transistors have now substantially
exceeded the die sizes of the chips being fabricated with them. Combined
with the ability to integrate billions of transistors on the same die,
this size-wavelength cross-over has produced a unique opportunity for
completely new architectures and topologies, which were previously
impractical due the traditional partitioning of various blocks in
conventional design. These holistic circuits combine electromagnetics,
device physics, digital/analog circuits, and system architecture in one
place and produces orders of magnitude improvement in performance over
the existing solutions. These circuits leverage ideas of parallelism,
reconfigurablility, concurrency, self-healing, and stacking in more
regular and periodic on-chip structures that are more compatible to
modern fabrication processes and novel design and optimization
approaches. In this talk, we discuss some of these opportunities and
their associated challenges in some detail through a few examples in the
areas of high-frequency power generation, efficient on-chip radiators,
silicon-based THz imaging, self-healing system, versatile multi-modality
(plastic, air, copper) interconnects, and biomedical sensors. 

Bio

Ali Hajimiri (IEEE Fellow) 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 Stanford University in 1996 and
1998, respectively. He has been with Philips Semiconductors, where he
worked on a BiCMOS chipset for GSM and cellular units from 1993 to 1994.
In 1995, he was with Sun Microsystems working on the UltraSPARC
microprocessor's cache RAM design methodology. During the summer of
1997, he was 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 Thomas G. Myers Professor of Electrical
Engineering and the director of the Microelectronics Laboratory. His
research interests are high-speed and RF integrated circuits for
applications in sensors, biomedical devices and communication systems.
Hajimiri is the author of "The Design of Low Noise Oscillators" (Boston,
MA: Springer, 1999) and has authored and coauthored more than 100
referreed journal and conference technical articles. He holds more than
50 U.S. and European patents.

Hajimiri was selected to the TR35 top innovator's list (formerly TR100)
in 2004. He is a Fellow of IEEE and has served as a distinguished
lecturer of the IEEE Solid-State and Microwave Societies. He is the
recipient of Caltech's Graduate Students Council Teaching and Mentoring
award as well as the Associated Students of Caltech 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 of 2004, the International Solid-State Circuits Conference (ISSCC)
Jack Kilby Outstanding 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 NSF CAREER award and Okawa Foundation award. In 2002,
he co-founded Axiom Microdevices Inc., whose fully integrated CMOS PA
has shipped more than 150 million units, and was acquired by Skyworks
Inc. in 2009.
