In-fibre analogue optical processing for AI

Israeli start-up CogniFiber aims to perform analogue AI calculations optically inside special multiple-core optical fibres. The many cores are shaped and spaced inside a single fibre to enhance specific interactions. “The fibre enables to perform several types of functions which are essential to neural-networks computation,” company CEO and co-founder Eyal Cohen told Electronics Weekly. “Out of many possibilities, ...

Docking connector copes with 2mm of misalignment

German connector maker ODU has introduced a modular connector for docking systems that can handle ±4mm of radial play to allow for misalignment. 1mm of axial compensation is also available, as is optional grounding up to 10mm2. Called P4+, and part of its Silver-Line product family, the frame “ensures a durable interface for at least ...

Cambridge GaN Devices funded to make server power ICs

Cambridge GaN Devices has won government funding to develop a GaN power IC for server PSUs – and its first devices have been revealed. The company is fabless, and using its in-house intellectual property to improve the gate drive characteristics of GaN power transistors built on standard GaN foundry processes, by integrating further active devices ...

Passive radiative cooling improves high-end solar cells

Pusan National University in Korea is increasing the efficiency of solar cells by bouncing heat back into the sky. “Standing in the sun all day, solar cells often become very heated,” according to the university. “Over time, this degrades them and lowers their power-conversion efficiency. Integrating radiative coolers can solve this problem without energy consumption.” ...

7x7mm chip delivers 2x100W stereo

Infineon has created a 7 x 7mm multi-chip module that can deliver two audio channels of up to 100W each. Called MA5332MS, the company claims 95% for the Class-D amplifier when driving that power into 4Ω loads (10% THD+N, ±36.5V supply). Looking at the data sheet, up to 90W is available with <0.1% THD+N. Providing the load ...

Flexible stretchy supercapacitors

The University of Surrey has created a flexible and stretchy supercapacitor “that can be easily integrated into footwear, clothing, and accessories”, it said. Building one involves transferring aligned carbon nanotube arrays from a silicon wafer to a PDMS (polydimethylsiloxane) matrix in which they are partly embedded for robustness. This is then electro-coated with polyaniline to improve ...
