‘Zeptogram’ caught the eye at ISSCC 2022 conference last week, as researchers from French lab CEA-Leti produced a mass sensor with 170zg resolution for weighing molecules. Not only did they make one such sensitive weighing scale, but 1,024 of them in an array which can be scanned at high speed. The weighing part had been ...

The fastest bendable 8bit thin-film microcontroller was describe at the International Solid-State Circuits Conference this week. Designed by Belgian research lab Imec and nearby university KU Leuven, it was made by UK-based PragmatIC Semiconductor. Called Flex6502, is has 16,000 0.8µm gate-length IGZO (indium gallium zinc oxide) transistors over a 4.5 x 5.5mm active area (see photo, ...

EPC is offering a three-phase motor driver evaluation board built around 80V 3.6mΩ GaN power transistors, sized for drones, robotics and e-bikes. “The small size of this inverter allows integration into the motor housing resulting in the lowest EMI, highest density and lowest weight,” said the company. Called EPC9167HC, the design uses two paralleled EPC2065 ...

Murata has managed to compress 4.3μF into a three-terminal 0402 (1005 metric) package, and qualified it for automotive use. This is the surface-mount equivalent of a feed-through capacitor, with the end terminals connected together by a low-resistance direct path. This path is one end of the capacitor, whose other end is to be grounded via ...

A blisteringly fast 400V monolithic gallium nitride power buck converter featured at the International Solid-State Circuit Conference (ISSCC) this week. Its figures speak for themselves: 50MHz operation, sub-200ps dead-time, and 120V/ns slew rate at the switching node. The child of National Chiao Tung University and Realtek Semiconductor, both in Taiwan, the IC is GaN-on-silicon, combining a ...

At ISSCC 2022, the Leibniz University of Hannover presented a novel 50-60Hz universal mains ac-dc power supply that has almost all of its components on a single 3 x 7mm 0.18μm silicon-on-insulator die. The only external components are the output inductor and capacitor, both low-voltage parts. It can produce an adjustable 3.3 to 10Vdc from ...

It takes a lot of effort to avoid machine learning processors at this year’s IEEE International Solid-State Circuits Conference, as they popped up not only amongst digital processing papers, but also next to memory and analogue papers. For example, of all the thousands of companies designing ICs around the world, only four were invited to ...
