What a year it has been for operational amplifiers, those versatile circuits that can be hooked up to your design in hundreds of ways. Several companies have introduced upwards of 50 different op amp products in 2003 with predictions to introduce similar numbers in 2004. In just the 100+ MHz region there were more than 150 new op amp introductions from the suppliers this year.

Op amps are available for almost every design need you have. Design engineers tend to take them for granted because they expect that there will be one for just the design they are building. However, no matter what op amp suppliers provide engineers always want it tweaked a little bit so it works just right for their application.
Has the analog job market emerged into daylight? Certainly brighter times are upon us

At the height of communications funding bubble, designers of Serdes, CDR (clock-data recovery) and PLL (phase-locked loops) could count on receiving 10 job offers almost as soon as they flashed their resumes, writes analog recruiter, Gary Fowler. While the comms bubble has burst, there remain a number of openings for designers with solid analog experience. With a turnaround upon us, there a even more opportunities in WiFi and UWB, he says.
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.
