Abstract:
After Maxwell reunified the Electro-magnetic spectrum in the 1850s,
the spectrum broke on frequency lines into separate, specialized and
mature disciplines of study. Almost a century and half later, we see a
reunification of electromagnetism in one single platform, opening up
opportunities to create cutting-edge technology for the
next-generation systems. Having the ability to synthesize, control and
manipulate such a large portion of the spectrum (DC-THz) with a
billion transistors in a single platform, silicon, opens up a plethora
of opportunities spanning a wide range of applications in sensing,
imaging, spectroscopy, medical diagnostics, communication and beyond.
Such unprecedented levels of integration can be leveraged only we
remove the artificial partitions among various levels of abstraction
in system design such as analog, digital, electromagnetics, antenna,
communication and control theory and take a holistic approach. 

In this talk, I will show some practical examples how such an approach
enables us to go beyond transistor speed limits into the terahertz
frequency range (0.3-3 THz), demonstrating the first CMOS THz
beam-scanning array, an all-silicon active terahertz imaging system
and generation and radiation of pico-second pulses capable of dynamic
spectral shaping. The intersection of analog, digital and RF creates
new opportunities for novel and robust system design and, we will
discuss a fully integrated, closed loop and autonomous self-healing
mm-wave power amplifier capable mitigating process variations, load
mismatches and unintentional failures. If time permits, we will
discuss how manipulating optical fields in silicon can lead to
multiplexed sensor arrays in CMOS for bio-molecular diagnostics.


Bio: 
Kaushik Sengupta received the B.Tech. and M.Tech. degrees in
Electronics and Electrical Communication engineering from the Indian
Institute of Technology (IIT), Kharagpur, India, both in 2007, and the
M.S. and Ph.D. degrees in electrical engineering from the California
Institute of Technology, Pasadena, CA, USA, in 2008 and 2012,
respectively. 

In February 2013, he joined the faculty of the Department of
Electrical Engineering, Princeton University, Princeton, NJ, USA. His
research interests are in the areas of high-frequency integrated
circuits (ICs), electromagnetics, optics for various applications in
sensing, imaging and high-speed communication. Dr. Sengupta was the
recipient of the IBM Ph.D. fellowship (2011–2012), the IEEE
Solid-State Circuits Society Predoctoral Achievement Award, the IEEE
Microwave Theory and Techniques Society (IEEE MTT-S) Graduate
Fellowship, and the Analog Devices Outstanding Student Designer Award
(2011). He was also the recipient of the Charles Wilts Prize in 2013
from the Department of Electrical Engineering, California Institute of
Technology for the best PhD award in Electrical Engineering. He was
selected in Princeton Engineering Commendation List for Outstanding
Teaching in 2014. He was also the recipient of the Prime Minister Gold
Medal Award of the Indian Institute of Technology (IIT) (2007), the
California Institute of Technology Institute Fellowship, , and the
IEEE MTT-S Undergraduate Fellowship (2006). He was the corecipient of
the IEEE RFIC Symposium Best Student Paper Award in 2012 and the IEEE
Microwave Prize in 2015 for the best paper in IEEE Transactions on
Microwave Theory and Techniques published in 2013.
