UK neutron scientists are tackling the challenge of cosmic radiation and its damaging effect on sensitive microchips in the aviation industry in the drive to develop more robust electronic equipment. Accelerated testing of microelectronic components at the Science and Technology Facilities Council’s (STFC) ISIS neutron research centre replicates the...

One oft-cited maxim in the communications world states that standardization is the enemy of innovation: its premise is that once something is standardized there is, by definition, no room to alter or improve it and hence no remaining freedom in which to innovate. Indeed, this is frequently cited as...

In 2006, it appeared that the market launch of ultra-wideband (UWB) was imminent. Several factors conspired to delay that, but ABI Research now expects UWB to see very strong growth starting in 2008, finding its first success in laptops and computer peripherals and eventually in mobile handsets. Forecasts indicate...

From a mobile operator perspective, mobile WiMAX or 802.16e provides more of a service complement than a competitive threat, reports In-Stat. The mobile standard for WiMAX has been the subject of debate since its inception, the high-tech market research firm says. Mobile operators and vendors have disputed how this...

Industry News The IEEE International Reliability Physics Symposium’s (IRPS) 46 th annual conference will feature new technical sessions and invited papers on the latest microelectronic reliability issues. This year’s IRPS takes place from April 27 through May 1, 2008, at the Hyatt Regency Phoenix at Civic Plaza in Phoenix,...

Modern electronics use time bases for a wide variety of applications. Communications systems rely on time bases for modulation and demodulation of data, GPS systems rely on them for accurate positioning, and a host of other applications rely on time bases to manage the flow of data within their...

In modern digital wireless communication systems, such as IS-95, PCS, W-CDMA, OFDM and so on, power amplifiers have progressed towards having a wide bandwidth and a large number of carriers. Recently, orthogonal frequency division multiplexing (OFDM) modulation has become an attractive technique for transmitting information efficiently within a limited...

The quest for a low-noise, high-switching-speed synthesizer has become a common trend in modern wireless systems. A large division ratio is required for the feedback path of a conventional phase-locked loop (PLL) if microwave frequencies need to be synthesized. To mitigate the problem, an offset PLL architecture is often...

Class-E power amplifiers (PA) offer high efficiency. However, with broadband load networks, their harmonic performance degrades. This article introduces a practical implementation to achieve high harmonic suppression in a broadband class-E amplifier design by combining a parallel-circuit load network with a reactance compensation technique. A three-stage power amplifier is...

The speed to market is critical to the success of any RFIC company. With more and more wireless standards proposed and adopted, the design cycles are actually getting shorter. It puts a lot of pressure on the RFIC team to come up with the design faster. In the digital...
