LoRaWAN Cellular NB-IoT Power Consumption Comparison

https://www.amihotechnology.com/lorawan-cellular-nb-iot-power-consumption-comparison/ The intent of this post is not to say which technology is better or worse. But, rather to show how Cellular IoT and LoRaWAN complement each other. Battery lifetime is by far one of the most important considerations for LPWAN applications because often it is very expensive to replace batteries physically. It will ruin

Finding the right power supply technology for your design | EDN

https://www.edn.com/design/power-management/4460362/Finding-the-right-power-supply-technology-for-your-design In 2016, each person on the planet purchased an average of 111 semiconductor chips or integrated circuits. As the number of chips climbs, so does the need for greater power, space, and cost efficiency. In response, power device manufacturers have continued to evolve silicon-based technologies and develop new, wide bandgap materials such as gallium-nitride

13 Companies announce NB-IoT Chips | Creative Connectivity

http://www.nickhunn.com/13-companies-announce-nb-iot-chips/ With thirteen different companies bringing chips to market, that’s an investment of around $200 million. Add to that the costs of the standardisation process, infrastructure development and initial market trials and it’s clear that somewhere between $500 million and $1 billion has already been spent on getting NB-IoT to the point where it is

In praise of the common-base: Bench quickie | EDN

https://www.edn.com/electronics-blogs/benchtalk/4460355/In-praise-of-the-common-base–Bench-quickie The common-base configuration is so little used, it doesn’t even register on many engineers’ radar. It is hard tp really learn and internalize a circuit until I have a need for it, and have done at least some small hands-on activity with it. This article describes how to test this type of circuit.

Why batteries are holding up tech breakthroughs — and what’s happening now

https://thenextweb.com/contributors/2018/02/21/batteries-holding-tech-breakthroughs-whats-happening-now/ Despite incremental advancements, batteries haven’t changed all that much over the past decade. Major brands are investing in better environmental efficiency, and small tweaks that improve storage and performance, but the typical “battery” is still fundamentally the same. There is stagnation in the realm of batteries.

Build Your Own Touchscreen IC Tester for Just $25 – Hackster’s Blog

https://blog.hackster.io/build-your-own-touchscreen-ic-tester-for-just-25-7f10fab3815b IC testers help you identify an unknown IC by testing its input and output against a database of known components. You can follow Akshay Baweja’s tutorial to build your own. The total build cost should be around $25, and you’ll need a Arduino Mega 2560, a touchscreen display with an SD card slot, an

High-speed digital: 112 is the new 56 | EDN

https://www.edn.com/design/test-and-measurement/4460312/High-speed-digital–112-is-the-new-56 EDN magazine reports that at DesignCon 2018, 112 Gbps was all over the conference and exhibit hall. Even just a year ago, engineers were still talking more about 56 Gbps speeds than 112. This year, all agree that 56 Gbps speeds have been achieved. It’s time to move on.

NRZ is dead, but not everywhere | EDN

https://www.edn.com/electronics-blogs/rowe-s-and-columns/4460291/NRZ-is-dead–but-not-everywhere PAM4 modulation is everywhere. “Five years ago, PAM4 was a concept” “PAM4 is being deployed everywhere except in short-reach links.” “DSP is enabling PAM4 optical channels” PAM4 has won the battle in fiber-optic and other medium and long-reach applications.

Should I Create a Proof-of-Concept Prototype for My New Product?

https://predictabledesigns.com/faq-should-i-create-a-proof-of-concept-poc-prototype-for-my-new-product/ As the name implies, the purpose of a proof-of-concept (POC) prototype is to prove your product concept. A POC answers if a product is feasible. In most cases a POC prototype is only used internally to determine the practicality of a new product. Customers will rarely see a POC prototype. So do you need
