PDN Impedance Tuning How to Achieve Target Impedance in Power Integrity PCB Design
In modern high-speed PCB design, PDN Impedance Tuning is critical for power integrity (PI). A poorly designed power distribution network (PDN) can lead to voltage droops, noise coupling, and system failures. At the heart of PDN design lies impedance tuning—the process of ensuring that the impedance of the power delivery path remains below a target…
