New Electronics brings you a selection of in depth Technology Articles, covering key issues and innovations within research & development, embedded design, power, communications design, test & measurement, programmable logic, system design and more.

Inspiring and intriguing, the new Information Age gallery at the Science Museum works at every level

Much has been written and discussed about the lack of engineers in the UK's educational pipeline. The accusatory finger is variously pointed at industry, schools, universities and government, but it is clear there needs to be a host of initiatives if we are likely to get anywhere near a solution. One immoveable imperative is that children will need to want to be engineers and scientists.

PCB based system brings increased flexibility to satellite test systems

The proliferation of artificial satellites is quite staggering; almost 7000 satellites have been deployed to date, around half are still in orbit and something like 1000 are still active. It's no exaggeration to say that modern life wouldn't be the same without satellite technology and so it's not surprising to learn it's a growing industry.

As process technologies shrink, the problems for analogue designers grow in complexity

Low voltage supply rails and strict design rules are changing the way designers need to think about circuit design. It is sweeping away old assumptions – it is a topsy-turvy world in which iterative topologies can be fast and where you can implement analogue circuits using digital synthesis. Because of the complexity of the most advanced processes, some level of automated synthesis for analogue design has become almost essential.

The test requirements for assessing VoLTE call quality

The wireless industry is making significant investments to implement Voice over LTE (VoLTE) in 4G LTE networks. Alongside the need to at least match the audio quality of 2G or 3G legacy networks, it is important to ensure that a VoLTE call consumes a comparable amount of power.

Do display modules make sense?

Never before have embedded project specifications been more directly influenced by consumer experience. The attractiveness of the smartphone with its nifty, gesture based interface has translated directly to the desirability of a similar class of HMI on a wide universe of industrial, medical and other embedded products. At the same time, just as we are personally connected to the internet in many ways, we now have a parallel Internet of Things for the billions of embedded computers around us.

Eight technologies which could allow the UK to take a market lead

Last year, while he was still minister for universities and science, David Willetts wrote a paper for the 'think tank' Policy Exchange in which he argued that the UK was either leading the world – or had the opportunity to lead – in a number of technologies. The paper's title summed it up – 'Eight Great Technologies'.

Complex devices require complex packaging

Packaging a semiconductor component is becoming an increasingly complex business. It's never been an easy task, even for simple devices, but when it comes to leading edge products, there is more than a degree of boundary pushing involved.

How an EV evolution is set to get more buyers buying

More well known car brands are introducing electric vehicles and plug in hybrids (PHEVs), driven by factors such as the EU's legislation to reduce fleet average CO2 emissions to 95g/km by 2021. PHEVs can offer very high mpg and qualify for zero excise duty, but are expensive compared to conventional cars in the same market category. Pure battery EVs (BEVs), meanwhile, offer complete freedom from the internal combustion engine, but driving range between recharges is limited.

Choosing the right A/D converter architecture and IP to meet the latest high speed wireless standards

Internet enabled mobile devices are continuing to become more prevalent in the modern world. With this proliferation of smart, connected devices – many of which are battery powered – comes a greater need for power efficient wireless transceivers. In addition to meeting stringent power specifications, RF system designers must also ensure that their devices adhere to the latest wireless standards, including Long Term Evolution (LTE) and Wi-Fi.

Preview: electronica 2014

It's 50 years since electronica first opened its doors for business. Since that first event in 1964, it has grown to its current position as the leading show and conference addressing electronic components, systems and applications.

Design group aims to develop supplies for the low power sector

When it comes to power supplies rated at 250W and beyond targeted at medical and industrial applications, TDK Lambda claims to hold the largest market share. But tackling the much larger market for less powerful supplies has presented a problem for the company, as its product offering in this range has been determined largely by what has come out of the parent company in Japan.

Smart traffic systems help ease congestion

It is unlikely to be of much comfort when you're next in a traffic jam to know there is a plethora of traffic monitoring and management technologies out there trying to detect the build up of traffic and help you on your way.

Why do multicore systems make it harder to find and diagnose bugs?

Concurrency takes on a new dimension in multicore platforms, since true parallelism comes into play and communication between threads is often achieved using shared memory. Writing a correct concurrent program is notoriously difficult and the advent of multicore architectures makes it significantly harder again due to their added complexity.

Electronics Design Show 2014 preview

Building on the success of last year's inaugural show, the award winning Electronics Design Show promises to be even bigger and better in 2014, with the addition of technology showcase features that will offer an unrivalled opportunity to see, hear and discuss the latest electronic engineering developments.

The military CE marking conundrum

Many manufacturers and suppliers of electronic military equipment are confused about CE marking requirements, with many presuming their products are exempt from normal commercial regulations. However, the interpretation of military equipment exemption has changed recently.
