Diodes has used post-package trimming to hone a 25μV maximum offset 9.5nV√Hz (1kHz) noise dual op amp with 5.5MHz bandwidth. Called AS2376Q, the device is intended for filtering and control, particularly in automotive applications – it is qualified AEC-Q100 Grade 1 and has automotive-grade supporting PPAPs. Both input and output are rail-to-rail, and operation is over 2.2 to 5.5V (950μA ...

Yang Shining (pictured) the CEO of Yangtze Memory (YMTC) is reported by DigiTimes to have resigned for personal reasons. Yang was once described as a ‘genius’ by Zhao Weiguo the former chairman of Tsinghua Unigroup which owns YMTC. Zhao was detained by the Chinese authorities in July for investigation. Yang has had a distinguished semiconductor career. He is a graduate ...

Harvard scientists have managed to create a processing circuit usign ionics rather than electronics. Working with biotech start-up DNA Script, they designed an ionic transistor which consists of an aqueous solution of quinone molecules, interfaced with two concentric ring electrodes with a centre disc electrode (see photo). The ring electrodes electrochemically lower and tune the local pH around the centre disc ...

IC intellectual property company SiFive has licensed Segger’s emRun++ C++ library for Risc-V, a library optimised for GCC/LLVM-based tool chains and embedded systems, based on the emRun and emFloat runtime and floating-point libraries. This follows on from last year, when SiFive licensed Segger’s emRun C runtime library for use in its Risc-V IDE and Tool packages. “It was an easy ...

The tech industry loves to invent new words or re-purpose old ones. One of the currently fashionable words is pivot – meaning you’ve changed course. Silicon Valley’s most famous PR man – Regis McKenna – who taught Intel and Apple about how to present themselves – is amusing about pivot. “‘Pivot’ is a much more acceptable term than ‘I’m changing ...

STMicroelectronics has started a second STM32 entry on GitHub alongside its official STM32 GitHub for the microcontroller family. Called STM32 Hotspot, it “contains non-productised code created by ST’s in-house engineers, originally written for purposes such as exhibition demonstrations and proof-of-concept models. Code examples like these would typically not be shared outside ST,” according to the company. There are 27 repositories ...

Kioxia will cut NAND production at its Yokkaichi and Kitakami fabs by about 30% in October. “The company will continue to review and adjust operations as needed,” it said. The  Yokkaichi and Kitakami plants are operated jointly with Western Digital. NAND prices are expected to fall between 13% and 18% in Q4.

Stackpole has extended its CSRF2817 range of surface-mount foil-on-ceramic resistors up to 100mΩ – it continues to reach down to 3mΩ. “For devices that need somewhat higher resistance values, high current handling, low temperature coefficient and high stability, finding cost effective solutions can be challenging,” according to the company. “Film type resistors will not have high current handling, and all ...

Korean chip production fell 1.7% in August y-o-y after a  17.3% rise  in July, according to  Statistics Korea. It is the first fall in output since January 2018. Inventories increased  67.3% in August while factory  shipments fell 20.4%. DRAM prices fell 18% iin Q3 and NAND is expected to fall up to 13-20% in Q4.

Graphcore, the seven year-old Bristol server chip startup which has raised $730 million, is to cut jobs. “Graphcore has significant cash reserves and is well positioned to take advantage of the AI compute opportunity,” says a company statement, “however the macroeconomic backdrop is extremely challenging. This means making some hard but necessary decisions around our priorities to put us in ...
