Nanorod LEDs could make multifunctional displays
Nanorod LEDs could make multifunctional displays

Cell phones and other devices could soon be controlled with touchless gestures and charge themselves using ambient light, according to researchers at the University of Illinois and Dow Electronic Materials. Made of nanorods arranged in a thin film, LEDs arrays that can both emit and detect light could enable new interactive functions and multitasking devices. The 5nm nanorods are made of three types of semiconductor material. One type emits and absorbs visible light. The other two s...

Chip to secure wireless chargers against counterfeit
Chip to secure wireless chargers against counterfeit

To resolve the problem of counterfeit wireless chargers - which could cause power surges that fry a device’s circuitry – researchers from MIT’s Microsystems Technology Laboratories have built a chip that blocks attempts to wirelessly charge a device’s battery unless the charger first provides cryptographic authentication. The same technology also solves another problem with wireless chargers. When two devices share a single charger, if they are different distances f...

Software package allows power supply designers to get smart
Software package allows power supply designers to get smart

Starting from a few specifications, such as required power or the entry and exit voltages, SmartCtrl – a program developed by the Universidad Carlos III de Madrid (UCM) – is said to provide those designing electronic power converters with a predefined map of solutions. This, say the developers, accelerates design work as engineers don’t need to resort to complex mathematical calculations. “The designer is provided with automatic code generation, which will give ...

‘Keep alive’ device draws power from sensor output
‘Keep alive’ device draws power from sensor output

A low-cost chip developed at the University of Bristol is said to extend battery life in sensors; in some cases, by more than 10 times. The patent pending UB20M voltage detector is a ‘keep-alive’ device which, when combined with a suitable sensor, is said to eliminate standby power by enabling zero-power sensing and listening. The developers say the device will allow designers to create circuits that can perform continuous monitoring without using battery power and to implement...

All digital PLL said to outperform comparable solutions
All digital PLL said to outperform comparable solutions

Imec, Holst Centre and Rohm have described an all-digital phase-locked loop (ADPLL) for IoT radio transceivers at ISSCC 2017 in San Francisco. According to the partners, a PLL is not only one of the major power consumers in a radio, but can also take up to 30% of the radio area. In contrast, the ADPLL occupies just 0.18mm2 in a 40nm CMOS process and consumes 0.67mW while performing better than digital PLLs. PLLs have traditionally been analogue components, although researchers have been...
