Emissions from small gasoline engines could be reduced using a new analog chip that Freescale Semiconductor introduced at a technology forum in Shenzhen, China.
Use it or slew it
Articles 8/24/2009 2 comments
Kendall Castor-Perry sheds light on op amp slew rates, explaining why you may need to specify a slew rate that's much higher than the signal is required to move at, particularly for circuits whose performance is sensitive to the gain bandwidth of the amplifier.

Kendall Castor-Perry discusses the value of spreadsheets when calculating component values. Kendall shares trusted cell formulae that can be used in your spreadsheets to determine E96 component values in filter designs.
Lowest power op amp claimed
Articles 8/10/2009 Post a comment
National Semiconductor Corp. (Santa Clara, Calif.) claims to be offering the industry's lowest power consumption operational amplifier (op amp), at 552 nanowatts (nW).
There’s a further cool thing you can do with a spreadsheet that most SPICEs can’t. That’s to use the spreadsheet ‘solver’ functionality to adjust component values in the search for a better-fitting circuit – or even to find a set of component values for a circuit you can’t otherwise design.
Infineon MOSFETs have been embedded into PC boards by Schweizer Electronic AG
You now need to adjust component values to achieve some system goal, such as predefined frequency response or time behaviour, and there’s no closed method for working out those values.
As a member of the electronics design community, I am angry and disappointed with the recent deaths of 346 people due to the Boeing MAX 8 design
The theoretical advantages of GaN-based power transistors are now being realized in mainstream system designs. Power supplies for data centers and telecom switching racks are two application areas where GaN transistors show significant improvement in comparison to systems using best-in-class Silicon-based Superjunction devices.
