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 ...

Leti has used an active interposer as a modular and energy-efficient integration platform that can integrate large-scale chiplet-based computing systems such as HPC and big-data applications. A high level of performance in HPC and big-data technologies requires modular, scalable, energy-efficient, low-cost many-core systems. To scale out the architecture, existing techniques using 3D integration and chiplet ...

Q1 notebook production will fall 29-36% sequentially, says Digitimes Research, due to laboyr and component shortages caused by the coronavirus. Some notebook ODMs’ China plants have capacity utilisation of around 30% due to slow employee returns, the 14-day quarantine requirement of returning workers and the delayed resumption of production at suppliers of non-key components which ODMs ...

Imec and Ghent University have demonstrated a silicon analogue time-interleaver achieving signalling rates up to 100 Gbaud (200Gb/s) at a power consumption of only 700mW using PAM-4 modulation. The architecture is a crucial building block for high-speed optical transceivers in future datacentres. Over the next few years, datacenters will upgrade their networks to cope with ...

TI today expanded its temperature sensing portfolio to include linear thermistors that deliver up to 50% higher accuracy than negative temperature coefficient (NTC) thermistors. The higher accuracy of TI’s thermistors enables operation closer to the thermal limits of the other components and the overall system, helping engineers maximise performance while reducing the BOM. NTC thermistors ...
