This guest column is the first of a series of topical comments and insights from Kendall Castor-Perry, an experienced analog designer, filter wizard, audio expert, systems engineer, technology marketer and product manager.
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.
