Abstract – There is a growing interest in terahertz and mm-wave systems for compact, low cost and energy efficient imaging, spectroscopy and high data rate communication. Unfortunately, today's solid-state technologies including silicon and compound semiconductors can barely cover the lower part of the terahertz band. In order to overcome this limitation, we have introduced systematic methodologies for designing circuits and components, such as signal sources and amplifiers operating close to and beyond the conventional limits of the devices. These circuit blocks can effectively generate and combine signals from multiple devices to achieve performances orders of magnitude better than the state of the art. As an example, we show the implementation of a 482 GHz oscillator with an output power of 160 W(-7.9 dBm) in 65 nm CMOS, and a 300 GHz frequency synthesizer with 7.9% locking range in 90 nm SiGe.

Abstract – In recent years, there has been a rapid innovation in the field of portable devices which has revolutionized the whole electronic market. The personalized gadgets such as smartphones are part of users’ life which contain sensitive data and private information. Privacy and protection of the data is a crucial task, consequently so many encryption techniques have been introduced to keep the data out of the hands of hackers. However, hackers employed new techniques that often proved the vulnerability of the crypto-processors. It is therefore imperative that system architects, circuit designers be aware of the security issue and be familiar with techniques to tackle such a rapidly growing threat. In light of the great importance to the new design dimension, security, this talk is proposed to provide an insight into and understanding of security challenges in design of digital circuits, identify the security requirements and present approaches leading to designing secure Cryptosystem-on-Chip (CoC).
Dr. Shahab Ardalan (IEEE M'02, SM'10) received his B.Sc. in EE at Amirkabir University of Technology, Iran in 1999, and his PhD degree at the University of Waterloo, Waterloo, Canada in 2007. Dr. Ardalan joined analog mixed signal research and development group in Gennum Corp. in 2007 where he was continuing his research activities on low-power, low-voltage circuits for high speed data and video broadcasting. In 2010, Dr. Ardalan joined San Jose State University as an assistant professor and director of center for analog and mixed signal where he is teaching and conducting research on topics of analog and mixed signal integrated circuits and integrated circuit security.
