Analog-to-digital converters (ADCs) are widely used in communication systems to interface analog and digital circuits. While the speed, power, and area of digital circuits directly benefit from the decreasing channel length of CMOS devices, analog circuits suffer from reduced headroom, lower intrinsic gain, and higher device mismatch. Consequently, it has been increasingly difficult to design high-speed and low-power pipelined ADCs using conventional op amps. This work presents a pipelined ADC that employs novel “charge-steering” op amps to relax the trade-offs among speed, noise, and power consumption. Such op amps afford a fourfold increase in speed and a twofold reduction in noise for a given power consumption and voltage gain. Using a new clock gating technique, the ADC digitally calibrates the nonlinearity and gain error at full speed. A prototype realized in 65-nm CMOS technology achieves a resolution of 10 bits with a sampling rate of 800 MHz, a power consumption of 19 mW, an SNDR of 52.2 dB at Nyquist, and an FoM of 53 fJ/conversion-step. A new background calibration technique is also proposed to accommodate temperature and supply variations. Current research efforts include extending the digital calibration techniques to ultra low-power neural amplifiers.

“Bionic Night at The Leonardo November 21″
Nov 21 @ 7:00 pm – 9:00 pm
"Bionic Night at The Leonardo November 21" @ The Leonardo | Salt Lake City | Utah | United States

BioUtah partners with The Leonardo and BODY WORLDS to host special Bionic Night this Friday at 7 p.m.

Lectures by Bionic Eye Researchers and Special Tour through The Cycle of Life with a Local Doctor who holds the Guinness Book of World Records as the Youngest to Graduate from Medical School at Age 17.


Salt Lake City, UT (November 19, 2014) – Can you live without a pulse? Could you see without any eyes? Next-generation bionics go beyond prosthetics, allowing us to not only run, jump and dance like never before, but to experience life in a completely new way—to be almost super-powered. Take part in a discussion and a personal tour through BODY WORLDS & The Cycle of Life as experts talk about the history and exciting evolution of Utah’s adaptive technologies.


On November 21, 7 p.m., BioUtah will partner with The Leonardo, BODY WORLDS & The Cycle of Life to host a special Bionics Night at The Leonardo. Speakers for the event include:

  • Dr. Richard Normann: Professor of Bioengineering at The University of Utah, who’s developing a way to help blind people see by implanting Utah Electrode Arrays into the visual cortex, and utilizing special glasses with a camera to send message signals to the arrays.
  • Dr. Gianluca Lazzi: Professor and chair of the Department of Electrical and Computer Engineering at the University of Utah and a part of the multi-institution team to create the first bionic eye.
  • Scott Bell: A local athlete and below-the-knee amputee will speak about adaptive technologies from a quality-of-life perspective.
  • Dr. Balamurali K Ambati: The official Utah Utes Team Ophthalmologist who graduated from medical school when he was 17. Dr. Ambati will lead a personal tour through the BODY WORLDS & The Cycle of Life exhibit to teach about the anatomy of the eye. Dr. Ambati specializes in cornea transplants, cataract extraction, keratoprosthesis (artificial cornea), LASIK, and other complex procedures of the cornea and anterior segment of the eye.

After the tour, attendees have the option to participate in an obstacle course to experience a glimpse into the everyday life of an individual with prosthetic limbs.

Cost: $19.95 includes ticket to BODY WORLDS & The Cycle of Life and special tour. Free to those who don’t want to take the tour. $14.95 ($5 off) for BioUtah members and for group sales.

Time: 7:00 p.m. Place: The Leonardo: 209 E. 500 S in downtown Salt Lake City

For group tickets (15 or more people) to Bionic Night at a $5 off per-ticket price, please email or call Jenie Skoy at 503-522-4071.

Bionic Night is one in a series of wellness-related events co-sponsored by The Leonardo and Body Worlds where local doctors, researchers, yoga practitioners and fitness experts address healthy living in a dynamic and interactive new way.

Other upcoming programs at The Leonardo include tomorrow night’s Sketch Night, November 20, 5-8 p.m. Draw in the spirit of Leonardo da Vinci, up-close-and-personal with human anatomical specimens guided by a master art teacher. (Held monthly every third Thursday!)

“BioUtah is honored to partner with BODY WORLDS & The Cycle of Life and The Leonardo to highlight some of the most exciting and dynamic work ever done in the Utah life science community, or in the world,” said Kimball Thomson, president & CEO of BioUtah.

“Utah leads the nation in medical research and Utahns are known far and wide for our healthy living habits,” said Jenie Skoy, BODY WORLDS & The Cycle of Life Communications Manager. Our goal is to provide unique opportunities to reinforce this belief that lifestyle choices people make—especially while young—lead to good health over the life-span. With BioUtah as a partner, we hope this event will help guests to further their understanding of the connection between art and science—in the spirit of Leonardo da Vinci.”

BioUtah members and all others are invited to participate in these events and to tour The Leonardo’s newest exhibit, BODY WORLDS & The Cycle of Life, presented by Arches Health Plan.

Giovan Battista Vico, a philosopher and historian who lived across the XVII and XVIII centuries, was the first to note in his masterpiece “Scienza Nuova” (New Science) that the history of man and his endeavors follow a cyclical pattern. Economies, as well as the power of nations, have exhibited a clear and cyclical behavior. Electronic Design Automation (EDA) has not escaped this fundamental law. EDA started in the late 1960s when large companies such as IBM and Bell Laboratories were developing new products based on Integrated Circuit technology. The ICs of the time had only a few tens of transistors but the design costs were raising and the need to obtain circuit right the first time became clear. The scientific content of tools and methods for ICs ranged from physics to mathematics in a mix that is rare to see in any other engineering field.

EDA technology advances have oscillated between verification and synthesis, the perception in the mind of the electronic design community of EDA has been rising and falling in a regular pattern, EDA companies have risen and declined, the consideration of the financial community for EDA has been periodically increasing and decreasing, and the algorithms used in EDA have swung from general purpose techniques borrowed from mathematics, computer science, operation research, and artificial intelligence, to ad hoc techniques that leverage the nature of the specific design problem to be solved. I will show that progress is achieved when new methodologies crystallize, with new tools and techniques acting as catalysts, that the construction of layers of abstraction are the steps that have helped us reach new heights, that the progress of EDA technology has slowed down just when complexity has reached levels never seen before.

I will argue that the designer community must leave its traditional shores, under attack by the swarm of killer transistors (more than 1 Billion transistor circuits have been realized), and sail towards a new world where transistors have been tamed. The advances in technology have made it possible to dream about a “smart planet” where trillions of devices are available for humanity. Throughout the talk I will intersperse considerations about my scientific and industrial journey from theory oriented professor to “entrepreneur.”
