PDN Noise: PDN and Signal

PDN Noise: PDN and Signal

In a previous blog, I discussed a power design network’s (PDN) self and transfer impedances. Self impedance highlights anti-resonances causing a significant increase in the PDN’s impedance. The anti-resonances increase a design’s power, noise, and lessen performance. Transfer impedance shows the change in impedance from one location to another on the PDN structure. The higher transfer i... »
