• Rohm op-amp eliminates oscillation due to load capacitance.

  01-07-2020 17:03 via electronicsweekly.com
  
  Rohm is claiming “industry’s first high-speed op-amp that eliminates oscillation due to load capacitances” for its 10V/μs BD77501G – which is not quite true unless some further caveats are added as, for example, ADI’s ‘C-Load’ op-amps are stable with any capacitance – LT1364 can hit 1,000V/μs. Rohm’s branding for capacitive tolerance is ‘Nano Cap’. BD77501G is ...

• Commercial AI is likely to cheat you, unless trained not to

  01-07-2020 13:31 via electronicsweekly.com
  Artificial intelligence that tricks you into paying more for things has come under the academic spotlight in a project by Swiss lab EPFL and British partners. The research into unethical AI is from the point of view of companies that do not want their AI to give them a reputation for tricking people. It finds ...

• A step on the road to skyrmion memories

  01-07-2020 11:55 via electronicsweekly.com
  
  US researchers have manipulated fixed magnetic skyrmions using voltages, offering a possible route to skyrmion memory. Magnetic skyrmions are self-contained stable spin fields that share some characteristics with particles. They can be only a few nanometres across, and in certain circumstances can be created, destroyed and manipulated with very little energy, leading to them being ...

• O-RAN compatible DC/DC converters for RFPA

  01-07-2020 07:17 via electronicsweekly.com
  
  Flex Power Modules is working with OpenRAN, and O-RAN Alliance to broaden its range of isolated DC/DC converters for RFPA. The IEEE, says Flex Power, is stating that existing LTE RFPA solutions are not suitable for operation in the 5G range due to frequency incompatibility and, therefore, will not achieve high efficiency if use continues. ...

• Murata claims smallest MLCC

  01-07-2020 07:12 via electronicsweekly.com
  
  Murata announces the development of what it believes to be the world’s smallest, laminated multilayer ceramic capacitor (MLCC) with a capacitance value of 1.0 μF in the 01005 inch size (0402M) measuring just 0.4 x 0.2mm x 0.2mm. The GRM022R60G105ME01 with a rated voltage of 4 Vdc is already in mass production and the GRM022R60J105M, ...
