Long term evolution (LTE) is firmly on course to be the dominant wireless communications standard in the next decade. There is overwhelming operator commitment to adopting the LTE standard and capitalising on the unquestionable benefits it will bring to their subscribers, even more so than was demonstrated for its 3G predecessors.
Selecting the best isolated brick DC/DC converter for an application can pose a challenging task for the design engineer. There are a number of circumstances that can motivate a particular choice. These could be transient response, efficiency, environmental conditions, or mechanical packaging.
Today, switch manufacturers are no longer developing just the switch. Original equipment manufacturers are frequently requesting that switch manufacturers develop the complete module, which may include an electro-mechanical switch or sensor, complementary electronics, a source of illumination, and a means of connection.
USB is the interface of choice for many of today’s consumer electronics products. Everything from cameras, to telephones and media players, as well as portable navigation devices use USB. Even devices with wireless interfaces, such as a Bluetooth phones, need to be connected to charge their batteries. USB provides the perfect interface: it is in widespread use and has a very well defined connector that makes it easy for both carmakers and device makers to use.
From smartphones to netbooks and everything in between, mobile devices are rapidly changing the way in which the world communicates. New platforms, operating systems and application frameworks are altering the embedded mobile playing field, driving the need for developers to stay ahead of market trends and end-user expectations. The new game has developers more focused on understanding the different technologies being used, and how each can create enriched mobile experiences that match to shifting end-user demands.
Given the improved performance of modern parts and packaging, how much certification and categorization does a product intended for operation in a harsh environment require?
Much has been written about the efficiency of Class D amplifiers, with figures of 90 percent or greater being routinely quoted. Such numbers might seem to suggest that the efficiency problem of audio amplifiers has been well-solved by conventional Class D. However, a closer look shows that this is far from the truth, with these amplifiers frequently seeing only single-digit percentage efficiencies, in real product usage conditions.
With so much of the ongoing development work for hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV) and pure electric vehicles (EV) involving the use of lithium-ion (Li-ion) batteries, many discussions at OEMs, electronics suppliers and battery manufacturers focus on how best to structure battery monitoring and management systems.
India's space agency is planning the nation's first manned space flight for 2016, if it gets government approval of the project budget, an official said Thursday. The Indian Space Research Organization has sought 120 billion rupees ($2.6 billion) to put two astronauts in space for a week, spokesman S. Satish told The Associated Press.
Imitation Web sites of both Google and YouTube have emerged in China as the country faces off against the real Google over its local operations. YouTubecn.com offers videos from the real YouTube, which is blocked in China.
In today’s rapidly growing healthcare marketplace, portability and functionality are the name of the game when it comes to medical devices. Healthcare is steadily moving away from hospitals to the point of incident and into the patient’s home. Around the globe, physicians and patients are turning to low-cost telemedicine solutions that give patients the ability to safely and effectively monitor their own health.
Today’s advanced applications are creating an insatiable appetite for memory - driving the demand for new memory technology capabilities. As the market for more compact, more powerful electronic systems grows, designers are under increasing pressure to find new ways to fit the volume of code and data needed onto these shrinking devices.
Haiti is full of hard-working and industrious people just looking for a chance to break out of the vicious cycle of poverty and nonfunctional social systems that keep it the poorest country in the Western Hemisphere. They only need a hand up, not a hand out, to "jump over their own shadows" and build a nation that functions for all of its people.
Wireless transceiver technology is truly established in the automotive industry with Remote Keyless Entry (RKE) now a standard feature of even basic specification vehicles. Following on its heels has been Passive Keyless Entry (PKE), dual transceiver devices that combine remote entry and remote starting, and systems that enable features such as tyre pressure monitoring and car-to-home communications.
As demand for longer battery life in portable devices increases, engineers are continually challenged to design highly efficient point-of-load (POL) converters while maintaining or reducing board space. Adding to the challenge is the fact that many portable devices like laptop computers have wide input voltage variation.
