Function Generator Circuit Concepts, Part 1: First-Generation Function Generators (FGs)
Dennis Feucht  
11/9/2015   1 comment
Function generators (FGs) are measurement instruments in the category of waveform sources. They grew out of both a need for a versatile source of multiple waveshapes and from some interesting analog circuit combinations that generate three waveshapes: triangle-waves, square-waves, and sine-waves.
From Electronics to Math and Money Madness

In electronics, we are familiar with bounded ranges on circuit variables, yet the idea of infinity is also common in electronics theory and does not seem to invoke insanity among engineers. This is not the case, however, in other endeavors, and can be found in such varied places as mathematics and global finance.

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.
