Raging trench warfare
The rate of improvement in trench MOSFETs may be slowing down but, as Steve Rogerson found out, there are still some fighting the battle.
Ultra-thin is the new bulk
The quest for smaller, faster, cheaper integrated devices really drives the semiconductor industry from a commercial point of view; an ever-present burden on developers working on the next great process breakthrough. Philip Ling reports for ES Design magazine.
Gate drive transformers have high potential of 2700VDC
Gate drive transformers, claimed to be suitable for high efficiency DC/DC converters, have been introduced by Pulse Electronics.The PG1427 series, which consists of the PG1427.001NL, PG1427.002NL, PG1427.003NL and the PG1427.004NL, has a high potential of 2700VDC and functional insulation between the gate and the drive windings.
Circuit breaker for DC power grids investigated
There are many advantages to using direct current rather than the alternating current used today. For example, when using direct current there are 5-7% less losses in power grids and electric devices.Direct current also makes it possible to more efficiently feed electric energy from regenerative sources into power grids and energy storage and therefore it improves grid stability.
Industry’s first seven-channel, NMOS low-side driver
Texas Instruments introduces the industry’s first seven-channel, NMOS low-side driver, replacing standard Darlington transistor arrays with a power-efficient, drop-in compatible integrated circuit (IC). The TPL7407L replaces half of the transistor arrays required to drive high current loads, providing a new option for high voltage systems that previously required a number of transistor arrays or a motor driver.
World first – fully organic flexible OLED prototype from Plastic Logic at SID '14
The new display features 256 grey levels, and full 30fps image rendering. The display offers further proof that organic transistor technology will offer display makers the best path to truly flexible, ultra-thin, lightweight AMOLEDs.
Plastic Logic unveils next step in its organic flexible AMOLED demonstrator programme
Plastic Logic, experts in the development and industrialisation of flexible organic electronics, has shown the second in its series of all-plastic flexible AMOLED display demonstrators.
Nanoparticle ink suits room-temperature printing
A nanoparticle ink which can be used in room-temperature printing has been developed by MANA. Previously, nanoparticle inks could only be used inhigh-temperature printing because they were surrounded by non-conductive ligands and required annealing. Researchers have created ananoparticle ink surrounded by planar aromatic molecules which, therefore, does not require annealing.
The last piece of the puzzle
Thanks to a new process, a CMOS RF power amplifier has matched the performance of GaAs devices for the first time, resulting in new possibilities for reconfigurable RF front ends, reports Sally Ward-Foxton.
Could graphene FETs drive greater RF integration?
There is growing anticipation that graphene will soon emerge as a replacement for silicon, fuelled by its outstanding promise. Now, a lack of progress towards monolithic integration may have turned an important corner thanks to the latest R&D breakthroughs, as Philip Ling reports.
