"Star grounding," Elias whispered, realizing the error of his previous analysis. "They moved the return path."
Elias traced the signal path with his cursor. The previous revision had the feedback loop for the voltage sensor routed right past the switching node. It was a noise antenna. Rev 20 showed a "Kelvin connection"—a dedicated pair of traces for sensing that bypassed the high-current path entirely. lae801p rev 20 schematic better
In engineering, progress is measured in millivolts, degrees Celsius, and decibels. By those metrics, Rev 20 isn’t just better—it’s a benchmark. "Star grounding," Elias whispered, realizing the error of
