ISSCC 2020: 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 ...

DMASS reports decline across Europe as the UK is “unfazed by Brexit”

The European Semiconductor Distribution (DMASS) organisation reports a decline of 16% in semiconductor revenue (Q4/2019), bringing the year to a close with a fall of 4.4%. 2019 hit the brakes in the middle of the year and finished with a “steep decline” in semiconductor distribution revenues for Europe. Sales in the semiconductor distribution market fell ...

Flex announces miniature dc-dc converters for industrial applications

Flex has introduced families of miniature dc-dc converters for industrial applications: the pua-A, puc-B and pub-M. The devices are all isolating converters that provide output power of up to 1W, with no minimum load required. Efficiency is typically 84% (pua-A), 80% (puc-B) and 81% (pub-M) at full load. Input-to-output isolation voltage is 2000V (pua-A), 6000V ...

ISSCC 2020: 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 – simply 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 ...

ISSCC 2020: 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. Scroll down for ISSCC 2020 DLDOs. However, a team at Seoul National University has turned the tables with a novel ...

ISSCC 2020: GaN power chip integrates control circuits

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 ...
