How to Reduce Noise in Mixed-Signal PCB Designs?
Your Mixed-Signal PCB Passed Every Test—So Why Are the Readings Still Unstable? Your PCB powers up, the layout passes DRC, and manufacturing is complete. Yet during testing, ADC readings fluctuate, sensors become inaccurate, or audio signals contain unwanted noise. What caused the problem? In many cases, the issue isn’t the schematic—it’s the PCB layout. Poor
