ISSCC: Secure chip will not make a mistake in your lifetime, probably

Working toward automotive security, Samsung has produced a ‘physically unclonable function’ (PUF) for secure crypto key generation. PUFs are blocks within chips whose characteristics only manifest when powered. They are inherently and unpredictably randomised by process variation as they are made, in a way that makes each chip uncontrollably unique, but once manufactured the characteristic ...

ISSCC: Computational imaging by THz array

Researchers from the University of Wuppertal in Germany have created a THz signal source array for computational imaging, which allows a single-pixel camera – one THz receiver – to form images. This type of computational imaging involves bathing the object to be photographed in varying light fields and measuring the amplitude of light that passes ...

ISSCC: Analogue on-chip LDO beats back digital onslaught

While digital on-die point-of-load converters are trending, analogue designs are far from finished. Digital low-dropout (DLDO) regulators appeared a few years ago and looked to be the future for on‑die point‑of‑load regulators on digital chips (see ISSCC 2020 DLDOs further down). However, a team at Seoul National University has turned the tables with a novel agile ...

ISSCC: GaN power chip integrates control

A monolithic GaN mains power converter IC was the target of Leibniz University Hannover, which worked with Texas Instruments. And the result is a 15W off-line PSU that can feed a 30-60V LED string with 140‑190mA from 60-400V AC or DC. Efficiency is 95.6% at low input voltage, and not dropping below 87.8% all the ...

Dc-dc converters fit in L78 linear reg footprints for industrial apps

Wurth has added 36V input versions to its range of dc-dc converters that are pin-compatible with established 78xx linear regulators – although, at 8mm thick, they are fatter than their linear cousins. The parts are 173010335: 3.3V out, 6-36Vin, 87% max efficiency at 12Vin 173010535: 5V out, 8-36Vin, 92% max efficiency at 12Vin “The components ...

Pole-mounted server is sealed to IP65

Supermicro introduced a sealed pole-mounted server for 5G and ‘intelligent edge’ applications at Embedded World last week. Sealed to IP65, inside is a choice of Intel Xeon D or 2nd Gen Xeon Scalable processors, and three PCI-E expansion slots for GPU or FPGA accelerator cards. For example, the Xeon D-2183IT is a 100W TDP processors ...

Converted red LED cuts temperature droop for car rear lights

Osram has created a phosphor-converted red LED for car rear combination lamps – for fog lights, for example. It has moved to phosphor conversion, rather than native red emission, to beat temperature droop. The part is called Synios P2720 CR – the initials for ‘converted red’. “One of the main issues with monochromatic LEDs for ...

Gap filling thermal compound pours in

Electrolube has launched a pair of thermal gap fillers to improve heat transfer. GF300 offers 3.0W/m.K conductivity GF400 offers 4.0W/m.K They are both silicone-based and two-part – requiring a 1:1 mix from a 400ml double-plunger cartridge using hand or machine application. GF400 is also available in a 50ml version. Consistency is a soft flexible putty, ...

Soft robot tentacle is scarily effective

Researchers at the Harvard have created an octopus-inspired soft robotic arm that can grip and manipulate objects, learning that the taper of such arms is important. “Most previous research on octopus-inspired robots focused either on mimicking the suction or the movement of the arm, but not both,” said researcher August Domel. “Our research is the first to ...

Stretchable OLED display proof-of-concept from KAIST

An engineered substrate is the key to a stretchable OLED display built by Korean lab KAIST. Photo: the display bent over a fingerip The novel substrate is there to allow rigid pixels to be incorporated. “Traditional intrinsically stretchable OLEDs have commercial limitations due to their low efficiency in the electrical conductivity of the electrodes,” according ...
