Everyone’s Talking About Power
November 6, 2025 | Heidi Barnes, Keysight Technologies
Delivering power to a digital load is an AC function, not DC. That simple statement may be obvious, but the implications of how electricity travels to an electronic load are complicated. Dynamic loads with rapidly changing currents create electric and magnetic fields that adhere to Maxwell’s equations. Ground can be misleading and is probably better used for describing where one grows potatoes and carrots. Electrical currents have “return paths,” and the energy is traveling in the fields between the power rail and the return path.
Target Condition: Distribution of Power—Denounce the Ounce
November 5, 2025 | Kelly Dack, Target Condition
Have you ever wondered why the PCB design segment uses ounces to describe copper thickness? There’s a story behind all of this—a story that’s old, dusty, and more than a little absurd. (Note that I didn’t add “Like many of us.”) Legend has it that back in the days of copper tinkers and roofing tradesmen, the standard was set when a craftsman hammered out a sheet of copper until it weighed one ounce, when its area conveniently matched the square of the king’s foot.

The Shaughnessy Report: Watt About Power Integrity?
October 8, 2025 | Andy Shaughnessy, The Shaughnessy Report
Yes, that headline is the equivalent of a dad joke, but editors can’t pass up a chance to inject a little humor into a headline, and I had to take my shot. Power integrity (PI) problems are no joke. Current power demands are...
