The Myth about Ground 🗓

— IEEE EMC Society Distinguished Lecturer Talk –

IEEE EMC Society San Diego

Meeting Date: December 5, 2018
Time: 6:00 PM Networking & Food; 7:00 PM Presentation
Speaker: Dr. Zhiping Yang, Senior Hardware Manager at Google
Location: San Diego

Summary:
GROUND is widely used in high-speed circuit modeling and simulation. However, there are a lot of misconceptions and misunderstandings about ground in the high-speed circuit industry. Does ideal ground really exist? If not, why do we use it in simulations? Should we connect the reference node of S-parameter model to ideal ground? Is ground bounce real and well defined? Should we put partial inductance and resistance on the ground net? What can we do or cannot do with S-parameter model? These questions are commonly asked by high-speed circuit designers. Answers from different people may be quite different and even contradictory. In this presentation, these questions will be answered with some simple, but powerful examples. At the end, the audience should have a better understanding about the ground and how to use it in high-speed simulations.

Meeting Date: December 7, 2018
Time: 7:00 PM Networking; 8:00 PM Presentation
Speaker: Will Theunissen, Facebook Connectivity Labs
Location: Redondo Beach, California
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
For longer than two decades phased array designers have promised low cost approaches to phased array antennas. With LEO and MEO SATCOM constellations planned for service in the next few years, the demand for steerable beams with large apertures is going to require delivery on these promises. 5G requirements for array antennas have resulted in commercially viable volumes for those beamformer ICs. Even though SATCOM apertures are large, needing large numbers of modules, affordability continues to be a challenge. The talk will focus on Facebook Connectivity Lab (FBC) array antenna development and efforts working with beamformer IC suppliers to support the FBC mission of connecting the unconnected with SATCOM one of the potential vehicles. The talk also describes the lab and field testing of electrically steerable phased array antennas designed for implementation in multilayer circuit board architecture.

(cum laude) degrees from the University of Stellenbosch, Stellenbosch, South Africa, in 1988 and 1990, respectively, and the Ph.D. degree from the University of Pretoria, Pretoria, South Africa, in 2000, all in electrical engineering. He is currently an Antenna Engineer at Facebook Connectivity Labs in Northridge, CA. Previous employment includes Principal Engineer with Lockheed Martin Commercial Space and Researcher at The Ohio State University ElectroScience Laboratory, Columbus. His research interests include reflector and phased array antennas and software development for antenna synthesis and design.

Adaptive and Resilient Circuits for Improving Processor Performance, Energy Efficiency, and Yield 🗓

— Negative impact of these variations on processor performance, energy efficiency, and yield.

San Diego Section

Meeting Date: November 7, 2018
Time: 10:00AM Networking; 10:15 PM Presentation
Speaker: Keith Bowman
Location: San Diego
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary: Dynamic device, circuit, and system parameter variations degrade processor performance, energy efficiency, and yield across all market segments, ranging from small embedded cores in an Internet of Things (IoT) device to large CPUs in multicore servers. This seminar introduces the primary variations during the processor operational lifetime, including supply voltage droops, temperature changes, transistor aging, and workload fluctuations. This presentation then describes the negative impact of these variations on processor performance, energy efficiency, and yield. The wide dynamic voltage-frequency scaling (DVFS) range in today’s processors increases these effects. For future IoT edge processors, the low-cost packaging, voltage regulation with time-varying energy harvesters, wide temperature range, and long-lifetime requirements exacerbate these problems further. To mitigate the adverse effects from dynamic variations, this seminar presents adaptive and resilient circuits while highlighting the key design trade-offs and testing implications for product deployment.

Advances in Islet Transplantation as a Treatment for Diabetes 🗓

— Current approaches and development of stem cells for transplantation.

EMBS Chapter, IEEE Orange County Section

Meeting Date: October 17, 2018
Time: 6:30 PM Networking & Food; 7:00 PM Presentation
Speaker: Jonathan RT Lakey PhD, MSM, Professor of Surgery and Biomedical Engineering, UC Irvine
Location: Irvine

RSVP: requested, through website
Event Details: Eventbrite

Summary: Diabetes is the 4th leading cause of death in the United States. At present there is no cure for diabetes and the principal treatment is the delivery of artificial insulin guided by careful monitoring of blood glucose levels using blood-testing monitors. Despite best efforts at maintaining good blood glucose control, the health of many diabetics deteriorate in terms of advances in the secondary complications of diabetes including retinopathy, neuropathy and nephrology.

Transplantation of functional derived islet tissue, isolated from cadaveric organ donors, by the “Edmonton Protocol” restores euglycemia by replacing islet tissue lost to autoimmune destruction, at the expense of lifelong pharmaceutical immune suppression. These drugs have known side effects, including elevated risk of infections, lymphoma and other cancers, making the Edmonton protocol appropriate only for those diabetics with advanced life-threatening secondary complications.

Encapsulation of islets by biomaterials including alginate, derived from seaweed is viewed as the best approach to extending the Edmonton protocol to more type 1 diabetics since it would not require lifelong pharmaceutical immune suppression. The lecture will discuss current approaches in biomaterial research for protecting pancreatic islets.

The other significant issue facing islet transplantation is the source of insulin secreting cells. Advances in stem cell research have progressed so that there are recently developed protocols to convert stem cells into insulin producing cells. These stem cell derived islets could represent a significant source of cells for transplantation, however there are risks with stem cells including consistency in cell expansion protocols and the potential of differentiating into cancer or other type cells. It is key that any stem cells derived product is retrievable and is protected from immune response in an effective and carefully constructed biomaterial device. The second portion of the lecture will discuss current approaches and development of stem cells for transplantation.

Advances in both biomaterials for implantation and identifying a safe and consistent source of insulin producing cells represent key steps in islet transplantation technologies to advance our goal of finding a cure for diabetes.

Bio: Dr. Jonathan Lakey has had a long interest and research direction in cell and tissue transplantation with a focus on diabetes and islet transplantation. Dr. Lakey graduated from the University of Alberta (BSc, MSc, PhD) and received post post-doctoral training in Indianapolis and Seattle before returning to establish his research program at the University of Alberta.

Dr. Lakey is now the Director of Research and Associate Professor of Surgery at the University of California, Irvine. Dr. Lakey is now Director of the Clinical Islet Program at the University of California, Irvine, conducting the development of both the auto and allo islet transplant program.

He has been awarded research grants and awards for diabetes and transplantation research from the Alberta Heritage Foundation for Medical Research (AHFMR), Canadian Diabetes Association and the Juvenile Diabetes Foundation International (JDFI). Dr. Lakey values the mentoring of MSc and PhD students in his research laboratory and supported training of technicians from several research and islet laboratories worldwide.
