System Bits: Aug. 4
By Ann Mutschler - 04 Aug, 2015 - Comments: 0

Turning electric signals into light signals Transmitting large amounts of data, such as those needed to keep the internet running, requires high-performance modulators that turn electric signals into light signals, and now, researchers at ETH Zurich have developed a modulator they say is a hundred times smaller than conventional models. They reminded that in 1880, Alexander Graham Bell deve... » read more

Power/Performance Bits: June 30
By Jesse Allen - 30 Jun, 2015 - Comments: 0

Tiny, solar-powered sensors Last week, at the Symposia on VLSI Technology and Circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it, even at the extremely low power levels characteristic of tiny solar cells. Previous ultralow-power converters that used the same approach had efficiencies of only 40 or 50 percent. ... » read more

Dedicated ASIC Design Is Now Cost-Effective
By Mentor, a Siemens Business - 24 Jun, 2015 - Comments: 0

Current market and technology trends have increased the demand for mixed-signal ASICs. Smaller projects with modest design budgets are viable due to low cost design tools and easy access to flexible, mature IC processes. This is especially compelling for developing mixed-signal ASICs for cost-sensitive sensor applications for the Internet of things (IoT). This paper discusses how costs and risk... » read more

Japan: Finding Leadership In New Technology Areas

An emergency torch that lets you breathe while escaping a smoke-filled building; a car that shrinks to fit into parking spaces that aren't quite big enough: from extreme situations to everyday activities, Ansys' Justin Nescott features devices designed to make life easier and safer in his picks for week’s top five engineering articles. Check out the prosthetic foot that takes commands from se... » read more

Energy Harvesting Update
By Ed Sperling - 18 May, 2015 - Comments: 0

Manos Tentzeris, professor of electrical and computer engineering at the Georgia Institute of Technology, sat down with Semiconductor Engineering to discuss energy harvesting. What follows are excerpts of that conversation. SE: What is the state of energy harvesting and are we making progress. Tentzeris: The latest results are systems with efficiency up to 40% to 45% utilizing ambient UH... » read more

Challenges For The IIoT
By Ed Sperling - 07 May, 2015 - Comments: 0

Unlike the [getkc id="76" comment="Internet of Things"], which is largely still a collection of connected devices that don't always play well together, the Industrial Internet of Things ([getkc id="78" kc_name="IIoT"]) already is in heavy use and growing across a number of markets well outside of the usual markets associated with semiconductors. A Morgan Stanley "blue paper" report issued la... » read more

Manufacturing Bits: March 10

Hi-tech pens The University of California at San Diego has developed a hi-tech ballpoint pen. Researchers have taken off-the-shelf ballpoint pens and filled them with bio inks. With so-called enzymatic-ink-based roller pens, users are able to draw biocatalytic sensors on a surface. [caption id="attachment_18297" align="alignleft" width="300"] Researchers draw sensors capable of detecting... » read more

Mentor Graphics Buys Tanner EDA
By Ed Sperling - 26 Feb, 2015 - Comments: 4

By Ed Sperling & Brian Bailey [getentity id="22017" e_name="Mentor Graphics"] has just purchased [getentity id="22561" e_name="Tanner EDA"] for an undisclosed sum, according to sources close to the deal. The acquisition moves Mentor squarely into the analog and mixed signal tools world, while positioning it to play a much bigger role in the Internet of Things market. Mentor isn't t... » read more

Short-Range, Low-Power Sensors
By Ernest Worthman - 09 Dec, 2014 - Comments: 1

Over the last 10 years the world has done a remarkably good job of connecting the global wireless world. This is partly because of visionaries, partly because of marketers, and partly just because we can, but mostly because of convenience. We now never need be to be off the wide-area interconnected highway. The last decade has radically changed the way we live. The smartphone and its cousin, th... » read more
