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... »

PDN Design, Target Impedance and Path Finding for IC, Package, and PCB

I am fortunate to work with Prof. Madhavan Swaminathan, Founder, CTO, E-System Design, and inventor of our algorithms. Long ago, as an undergraduate engineering student at University of Illinois focused on integrated circuit (IC) design, I enrolled in the required ElectroMagnetics (EM) course to discover it was all about large antennas¹. At that time, silicon and EM classes were not synchronized ... »
