Regardless of end use case, Semenza said Samsung is leading the pack in development of flexible displays. LG is a close competitor and developing the screen for the Apple Watch, another flexible plastic-based display.

We’re talking about something around four feet tall here. So after they’d thought about it a bit, the challenging team ambled out. One of them was holding a potato chip bag (a crisp bag in the UK) in the palm of his hand. He reached into the chip bag with his other hand and pulled the four-foot Tiki Torch out of the little rascal. It was like Mary Poppins, but in front of a live audience and without a table to hide any shenanigans.

Now, you might say It must have been stuffed down his trousers.” Well, I don’t know about you, but I find it extremely difficult to walk normally with anything like a four-foot Tiki Torch stuffed down my pants. All I can say was that this portion of the act completely blew me away — I’m still shaking my head in disbelieve. Did you see that episode? If so, do you have any idea how it was done?

BARCELONA – Decisions on how to use 500 MHz to 1,000 MHz of additional spectrum for current and future 5G services must evolve with consensus among multiple industries according to a panel of carriers and regulators speaking at the Mobile World Congress.

Panelists called for collaboration to avoid what ITU Radiocommunication Bureau Director François Rancy called a seismic spectrum shakeup.”

We want to establish a stable framework so the decision we take at [the World Radiocommunications Conference] WRC will not be challenged at the next conference. These decisions are what enables trillions of dollars in investment to be made in radio communications networks, terminals, applications and services. I think the decision and amount of spectrum that will be made available by this coming conference for broadband mobile is actually in proportion of the mobile sector to demonstrate that they can share spectrum efficiently with incumbent services.

Mirroring Rancy’s call to share spectrum among a variety of industries a panel of experts from the cellular, satellite, broadcasting, and networking industries discussed how to best use spectrum.

Optimization, constraint managers and statistical centering tools were automated early-on and well accepted by analog designers. However, analog engineers are still reluctant to use automated layout tools, because they have their own secret sauce for how a layout should be done.

Engineers don’s want automated layout tools, because there is an aesthetic involved, that serves as a surrogate for correctness,” Rutenbar told us. Aesthetics of the layout is used for insurance that the circuit will work, because they have built similar circuits in the past that have proven to work well.”

For the future, according to Rutenbar, engineers need to accept automated layout tools, especially for the future advanced node SoCs. For instance, today discrete analog circuits are cheap because they are using design rules that are up to five nodes behind the state-of-the-art in digital processes. However, for the future SoCs with mixed signal circuits on-chip, analog designers are going to have to learn how to create well performing analog functions at 14-, 10-, 7- and even 5-nanometers. They will also have to start making analog FinFETs. The biggest problems facing analog engineers using analog FinFETs, according to Rutenbar, are electromigration, signal and power routing that cause unacceptable DC voltage drops and self-heating of power circuits, all of which could be solved by using automated layout tools.
