Standard Step-Motor Driver Interface Limits Performance

Increasingly elaborate Rube Goldberg schemes for controlling step-motors have developed over the years that try to pace stepping to avoid missteps. This direction of development is fundamentally misguided. This article tells why.
Can μCs Replace Analog Circuits?

The cult of DSPism believes that eventually there will be essentially no analog circuits, that all circuitry will be either digital, as microcontrollers (μCs), with mixed-technology ADCs and DACs. This article explores the possibilities and limitations on this viewpoint

Removing the vuvuzela narrow-band noise was presenting challenges to broadcast engineers
This article discusses how using a single synchronous buck controller can output the most common voltage rails, and accommodate a wide range of operating input voltages from 3V to 40V, and at a reasonable BOM cost.
This article explains how the latest-generation SiC FETs are ideally suited to new inverter designs with lower losses than IGBTs and proven robustness against short circuits, even at high temperatures and under repetitive stress
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.
