2018 Texas Analog Center of Excellence Symposium

Annual TxACE Symposium, October 22, 2018

As electronics continue to bridge the gap between the analog real world and digital information infrastructure, the entire $400 billion per year integrated circuits industry is evolving into an analog-digital mixed signal industry. This one-day symposium will examine trends, emerging opportunities and key challenges in analog integrated circuits and systems, as well as related technologies.

Transition Design for High Data Rate Links at Submillimeter Wave Frequencies

Rashaunda Henderson, Professor UT Dallas

Friday July 20 at 1:00 – 2:00 p.m. in the Osborne Conference Room ECSS 3.503


Rashaunda Henderson received the B.S.E.E. degree from Tuskegee University, Tuskegee, AL, in 1992, and the M.S. and Ph.D. degrees in electrical engineering from The University of Michigan, Ann Arbor, MI, in 1994 and 1999, respectively. From 1999 to 2007, she worked as a R&D device engineer at Freescale Semiconductor, formerly known as Motorola Semiconductor Product Sector. Since Fall 2007, she has been researching novel passive components and integration techniques for millimeter -wave circuits and systems. She advises a team of students in the design, fabrication and characterization of high performance passive components, antennas and packages for frequencies operating through 325 GHz. Dr. Henderson is a senior member of the IEEE and an elected member of the MTT-S Administrative Committee.


High data rate communication systems using electronic circuits have been demonstrated with carrier frequencies up to 100 GHz using flip-chip technology and plastic waveguides. Extending to higher frequencies from 100 to 350 GHz will benefit in higher bandwidths while requiring novel techniques to launch the signals using on-chip antennas. If standard dielectric waveguides are used, they will require multiple structures due to their band-limited nature. In addition, these waveguides do not include IC packaging, which is required for commercial system deployment. Providing a low cost transition realized in printed circuit board technology can reduce the overall costs.

This presentation highlights the design and characterization of vertical transitions to support a high data rate communication system operating at 180 and 315 GHz. Transmitter and receiver circuits have been designed in 65 nm CMOS technology and a dielectric waveguide study has been conducted using holey fiber technology. A vertical transition is used to guide the RF signal from the chip to the dielectric waveguide. Substrate integrated waveguide concepts are utilized to implement the transition with an on-chip cross dipole and holey fiber waveguide in cyclic olefin copolymer. Designs at 3 and 30 GHz have been used to understand performance and then scale up for the system configuration. To support the bandwidth and dual polarization scheme, quadruple ridge waveguide structures with air dielectric are being designed with advanced printed circuit board techniques.

Student Wins First Place at IEEE HOST

Doctoral student Kiruba Subramani recently earned a first place award at the 2018 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST).

Subramani’s “Performance Randomization for Preventing Hardware Trojan Attacks in Analog/RF Circuits” demonstration earned first place in the symposium’s Best Hardware Demonstration Category.

The demo was prepared by Subramani; Dr. Angelos Antonopoulus, a former postdoctoral researcher in electrical engineering; Dr. Aria Nostratinia, professor of electrical and computer engineering; and Dr. Yiorgos Makris, professor of electrical and computer engineering and leader of the Trusted and RELiable Architectures (TRELA) Research Laboratory, of which Subramani is a member.

Dr. Yu Liu, a former member of the TRELA lab, won the same competition in 2016 for his demonstration entitled “Hardware Trojans in Wireless Cryptographic ICs: Silicon Demonstration and Detection Evaluation.”

TxACE STARS: TxACE Workshop on Secure and Trusted Analog/RF Systems

The TxACE STARS Workshop format is designed to be highly interactive, featuring not only keynote talks but also panels, informal discussions, student posters, prototype demonstrations and break-out sessions. The outcome of the workshop will be a report authored by the various stakeholders, which can provide guidelines as the hardware security community expands its activities to cover the analog/mixed-signal/RF domain and its applications.
