Fired Trump Staffers Hold Reunion | The New Yorker


The event, which drew a crowd of approximately sixty-five thousand people, had been organized by the recently axed Secretary of State, Rex Tillerson.

“The turnout is just outstanding,” a beaming Tillerson told reporters. “Of course, most of these people didn’t have anything else to do.”

Time for a Reality Check to 5G Exuberance | Design News


.. these descriptions didn’t quite capture the essence of 5G, which is that it’s a collection of technologies and design approaches that are being pulled together under the auspices of the 3GPP to develop a standard to meet the ITR-U’s “IMT-2020” vision of what a connected world should be capable of.

To that end, it has put out a number of minimum requirements, such as a downlink rate of 20 Gbits/s, uplink rates of 20 Gbits/s, user-plane latency of 1 ms, control-plane latency of 20 ms (10 ms “encouraged”), the ability to support up to 1 million devices/km2, 90% reduction in network energy usage, 99.999% network availability, among many others.

The point is that 5G isn’t a “technology” per se, it’s a means of wringing the most out of available spectrum and be able to use that spectrum in a flexible, secure, reliable manner.

Under 5G, researchers, silicon providers, system designers, and test and measurement engineers are working to figure out how best to realize the IMT-2020 vision, which requires a rethink of everything, from the radio front end to the core network.

For A Successful Analog ASIC, First Weed Out the Pretenders | EEWeb Community


Analog behavior is described by sets of mathematical equations; digital is described by Boolean relationships. There is a distinct difference in the knowledge and skills required to fully understand and be competent in analog design.

Analog ASIC designers need to know in depth about semiconductor manufacturing technology, semiconductor material chemistry and physics, semiconductor device physics, electrical circuit theory, control and feedback, thermodynamics and much more, while digital circuit designers need to know about Boolean algebra, linear algebra, digital signal processing, synchronous and asynchronous systems, timing delays, etc..

I’m not trying to imply digital design is easy… it’s not… but it is different… very, very different.

Stories I’ve heard recently about Analog ASIC development failures are beyond horror… they’re devastating.

How to Read Data Sheets: Small-Signal BJTs | EEWeb Community


It must be admitted that diodes are useful devices, but they have one drawback for use in signal processing. This drawback is that every time you pass a signal through a diode, its amplitude gets a little lower. What we’d like is to have a semiconductor device that can amplify signals, and transistors are the most fundamental semiconductor devices that achieve this feat. Furthermore, without transistors, we wouldn’t have integrated circuits.

Explaining all the different types and applications of transistors would take an entire column (at least) in itself, but this Wikipedia entry provides a good history and overview.

If you perform a Google search for “transistor,” you will find multiple explanations, tutorials, etc. discussing how transistors work. I’ll touch on a few things during these discussions on their data sheets.

Oscilloscopes: Everything You Need to Know | EE Times


A long-time engineer at Teledyne LeCroy has written 32 articles (and counting) covering just about every aspect of using a digital oscilloscope.

Every electrical engineer, electronics hobbyist, maker, and EE student has used a digital storage oscilloscope (DSO), but today’s DSOs have so many features that using them can be daunting. Fortunately, there’s hope. EDN’s collection of oscilloscope articles by Arthur Pini can help you navigate the ins and outs of using a DSO.

The Unknown & Hidden Behaviors of Real-Time Systems | Design News


Engineering is not about guessing but for decades that is exactly how embedded software developers have developed their software. Engineering uses scientific principles to design, implement, and verify the design. Measurements are important if a design team is to be successful and efficient. The problem is that most development teams that I encounter take no real measurements of their software or really understand how it is behaving on their target processor despite there being the technologies available to do so.

Let me give a very simple example about how developers really have no idea what their software is doing without tracing their application.

eXpressWare PCIe software


The SISCI API (Software Infrastructure Shared-Memory Cluster Interconnect) enables customers to fully exploit the PCI Express programming model without having to spend months to develop device drivers and read low level PCIe switch chip specifications. The SISCI API offers a C programming API for shared/remote memory and device access, including reflective memory functionality. The SISCI API also supports direct peer to peer transfers and remote access to FPGAs, GPUs and NVMes communication over PCIe.

The SISCI API supports both local and networked communication, enabling applications to easily scale from a multiprocessor system to a larger PCIe network.

Dolphin’s SISCI Developers Kit consists of driver and API software, tools, benchmarks, documentation and source needed to develop your own embedded application utilizing the low latency and high performance of a PCI Express Network.

House Panel Approves Two Bills to Support Space Industry | Via Satellite


According to a November 2016 report by the Government Accountability Office (GAO), some companies have set up space support vehicle operations overseas because FAA regulations are too cumbersome. U.S. spaceports would like to attract those firms to operate out of their facilities, according to Posey’s office.

Companies involved in the space support market include Starfighters Aerospace, Stratolaunch, Virgin Galactic and Zero Gravity Corp.

The bills, which the committee approved unanimously March 22, now head to the full House for its consideration.

Jaguar’s Entry Signals Electric Vehicles Are Headed for the Mainstream | Design News


The battery system in the Jaguar I-PACE has 432 lithium ion pouch cells using a Nickel-Manganese-Cobalt battery chemistry. The pack is located under the floor of the I-PACE and weighs 1,329 pounds. Liquid-cooled, the pack produces 388 volts and has a total capacity of 90 kilowatt-hours.

Jaguar claims that its new electric can travel up to 240 miles on a charge and that charging to 80% capacity will take 10.1 hours with a 7 kW charger, and 85 minutes to charge to 80% when using a 50 kW charging system.
