Meeting Date: September 30, 2019
Time: 3:00 PM Presentation
Speaker: Shanthi Pavan, Professor of Electrical Engineering at IIT Madras
Location: San Diego, California
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
Continuous-time Delta-Sigma Modulators (CTDSMs) are a compelling choice for the design of high resolution analog-to-digital converters. Many delta-sigma architectures have been published (and continue to be invented). This leaves the designer with a bewildering array of choices, many of which seem to pull in opposite directions. Further, it is often difficult to make a clear comparison of various architectures, as they have been designed for dissimilar specifications, by different design groups, and in different technology nodes. This talk examines various alternatives for the design of power efficient single-loop continuous-time delta sigma converters.

Hybrid PLL Architectures and Implementations 🗓

–an analog proportional path in combination with a digital integral path

Meeting Date: September 26, 2019
Time: 6:30 PM Networking & Food; 7:00 PM Presentation
Speaker: Daniel Friedman
Location: San Diego
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
Depending on the target application and on implementation constraints, both conventional charge pump PLLs and high performance digital PLLs may be excellent implementation choices. Each design type offers significant technical advantages while also raising its own set of design challenges. For example, charge pump PLLs naturally provide a feedback signal that is linearly related to phase error, but typically demand the use of a physically large loop filter capacitor if lower loop bandwidths are desired. High performance digital PLLs solve the loop capacitor problem, but may require a high performance time-to-digital converter as part of the feedback linearization solution. This presentation will focus on the exploration of a hybrid PLL architecture, an approach which features an analog proportional path in combination with a digital integral path, thus in some way offering the best of both PLL worlds. The approach will be introduced and explored through the presentation of multiple high-performance integrated hybrid PLL implementations in deep submicron CMOS technologies.

Meeting Date: September 23, 2019
Time: 11:30AM Pizza & Networking;12:00 Presentation
Speaker: Dr. Eugene Grayver is a Principal Engineer in the Digital Communications Implementation Division at The Aerospace Corporation.
Location: El Segundo, California
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
Have you ever wanted to build a magic receiver that can get images from weather satellites, decode ship and airplane position messages, tune to your favorite FM station, and even navigate by GPS? All of this is possible today using a $50 USB dongle and a laptop running software defined radio (SDR) code. This talk will cover the basics of SDR – from getting an analog signal into a computer to the wide range of frameworks and tools available to process the signal. We will briefly discuss radios that can process gigabits and gigahertz of data, and tiny SDRs that can run off batteries. Software being the key part of SDR, we will discuss the challenges of executing real-time signal processing at high rates on COTS servers. Finally, we will touch on the evolution of SDRs as applied to 5G, ground stations, and how it all ends up in the ‘cloud.’

Dr. Eugene Grayver received his B.S from Caltech and a Ph.D. from UCLA, both in electrical engineering. In 2000, he was one of the founders of a semiconductor company working on low-power ASICs for multi-antenna 3G mobile receivers. In 2003, Eugene joined The Aerospace Corporation, where he is currently doing research into application of software defined radio (SDR) to a wide range of problems. Key aspects of his research include: reliable and resilient communications, navigation using GPS and fallback options when GPS is not available, flexible and upgradable processing for massively multi-user systems. His areas of expertise span from radio-frequency front ends to digital signal processing and up to the network connectivity. This research has led to hardware implementations of devices that support data rates from below 100 bps to 10 Gbps. He published a well-received book on SDR, multiple journal publications, and dozens of conference papers. Every year he chairs a session on software defined radio at an international IEEE conference. Eugene is a senior member of IEEE.

Robotics Meet Wireless Communications: Opportunities and Challenges 🗓

–3D imaging through walls with only drones and WiFi

IEEE Central Coast Event
register
Meeting Date: September 18, 2019
Time: 6:00 PM Networking & Food; 6:30 PM Presentation
Speaker: Professor Yasamin Mostofi Ph.D. of UCSB ECE
Location: Goleta, California
Cost: none
RSVP: requested, through website
Event Details: IEEE vTools

Summary:
Recent years have seen a great progress in the area of robotics. Communication signals are also ubiquitous these days. In this talk, I will explore the opportunities and challenges at this intersection, for sensing and communication. In the first part of the talk, I will focus on robotic sensing, and ask the following question “Can everyday communication signals, such as WiFi signals, give new sensing capabilities to unmanned vehicles?” For instance, imagine two unmanned vehicles arriving behind thick concrete walls. Can they image every square inch of the invisible area through the walls with only WiFi signals? I will show that this is indeed possible, and discuss how our methodology for the co-optimization of path planning and communication has enabled the first demonstration of 3D imaging through walls with only drones and WiFi. I will also discuss other new RF sensing capabilities that have emerged from our approach, such as the first demonstration of through-wall crowd counting and occupancy analytics with only WiFi signals, without relying on people to carry a device, or the first demonstration of person identification through walls with only WiFi signals.

In the second part of the talk, I will focus on communication-aware robotics, a term we coined to refer to robotic systems that explicitly take communication issues into account in their decision making. This is an emerging area of research that not only allows a team of unmanned vehicles to attain the desired connectivity during their operation, but can also extend the connectivity of the existing communication systems through the use of mobility. I will then discuss our latest results along this line. I will show how each robot can realistically model the impact of channel uncertainty for the purpose of path planning. I will then show how the unmanned vehicles can properly co-optimize their communication, sensing and navigation objectives under resource constraints. This co-optimized approach can result in a significant performance improvement and resource saving, as we shall see. I will also discuss the role of human collaboration in these networks.
