Summary: Thinned arrays are cost-effective implementations of imaging radars in autonomous-driving cars to achieve good angular/spatial resolutions. They feature reduced power, weights, processing loads, and overall production cost. The presentation relates to architectures and designs of imaging radars with thinned arrays via K-space measurements from radar returns concurrently. The imaging radars feature correlating interferometers made by elements of a thinned array, and digital beam forming (DBF) networks to put the K-space frequency components together properly. These DBF techniques are used in generating shaped beams such as low sidelobe spot beams, shaped area coverage beams, orthogonal beams, multiple hopping beams, and others.

Advanced Antenna Measurement Techniques Using Time Domain Transformation 🗓

— an “under-the-hood” review of time domain gating & its applications

IEEE EMC Society Distinguished Lecturer Talk

Meeting Date: February 13, 2019

Speaker: Mr. Zhong Chen of ETS-Lindgren, Cedar Park, Texas
Location: San Diego

RSVP: requested, through website
Event Details: IEEE vTools

Summary: Time domain gating is an effective technique to remove reflections in antenna measurements. The vector frequency response is transformed to time domain via inverse Fourier transforms, and a time domain gate can be applied. This function is included in commercial vector network analyzers. Although its applications seem straightforward, the implementations and limitations can feel like a “black-box”. We provide an “under-the-hood” review of this popular function, and explain the nuances in the time domain gating applications which can affect the measurement uncertainties. This presentation strives to provide an in-depth understanding of the time domain-gating algorithm. Topics discussed include aliases, resolution, typical EMC antenna time signatures, window functions, and time domain gate shapes, etc. We then discuss the gating band edge errors (or “edge effects”), mitigation techniques and the limitations of the post-gate renormalization method used in a VNA. We introduce an alternative edge mitigation method, which improves the accuracy for many antenna measurement applications. A live demonstration showing “real world” measurements will follow the presentation.

Ultra Low-power and Fast Wake-up MEMS-based Radios for the IoT 🗓

— Hear how high-Q MEMS resonators can be used to further reduce the power consumption of low-power radios.

IEEE OC Section Solid State Circuits Chapter

Meeting Date: Feb 21, 2019
Time: 6:00 PM Networking & Food; 6:30 PM Presentation

Location: Irvine, California

RSVP: requested, through website
Event Details: IEEE vTools

Summary: The emergence of the Internet of Things (IoT) poses stringent requirements on the energy consumption and has hence become the primary driver for low-power analog and RF circuit design. Implementation of increasingly complex functions under highly constrained power and area budgets, while circumventing the challenges posed by modern device technologies, makes the design of low-power RF CMOS radios ever more challenging. The power consumption of GHz short-range radios such as the ones used in BTLE has been significantly reduced in the last decade, but seems to level off at a few mW. This is still much too high to allow for continuous-time operation and duty cycling the radio is unavoidable in order to reach the tens of µW power consumption required for a multi-year autonomy. Duty-cycling unavoidably introduces some energy overhead that is wasted during turn-on and turn-off times. On the other hand, since there will be many radios that will share the same media, in order to avoid network congestion, the transmit times have to be made shorter by increasing the peak data rate. This results in the energy overhead becoming dominant. The use of PLL-free synthesizer using an RF MEMS frequency reference enables to minimize the wake-up and shutdown times to a few µs and hence minimize the energy-overhead. We will start with an introduction showing the requirements of IoT nodes with a focus on power consumption. We then will present how high-Q MEMS resonators can be used to further reduce the power consumption of low-power radios. After presenting the main features of high-Q MEMS resonators including bulk acoustic wave (BAW) resonators, we will show how several fundamental RF building blocks can benefit from them. Then we will present possible PLL-free transceiver architectures that take advantage of the very low phase noise and feature very short start-up time to greatly reduce the overhead energy.

Summary: Air quality monitoring has been historically left in the hands of local government agencies and the EPA. The size and cost of air quality monitoring systems have limited their number in any given area and enabled only regional and mostly delayed responses to air quality issues and their attendant health consequences. This talk will describe how one at risk Southern California community has joined with the South Coast Air Quality Management District to implement low cost air quality monitoring through a collaboration enabled by an EPA Science To Achieve Results (STAR) Grant. 30 web enabled low cost air quality monitors have been installed within a community of 10,000 seniors and are providing particulate matter measurements to inform their real time activities and help monitor nearby potential pollution sources such as adjacent freeway traffic and power generation plants.
