Many novices fall into the trap of simply \"stacking\" capacitors or obsessively chasing extremely low target impedance values, while overlooking the actual impact that layout details have on system stability. Through a high-speed processor project, we discovered that lead inductance\u2014caused by placing capacitors too far apart\u2014can severely degrade high-frequency performance. Spatial factors\u2014such as power plane segmentation and via return paths\u2014along with low..."}
