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... »

Path Finding: Who Performs and When?

Path Finding: Who Performs and When?

Microelectronic products all have mechanical, thermal and electrical properties that degrade until the device is permanently damaged. Path finding adds value to an end-product by pre-determining where the breaking points are, and if or how they can be enlarged. For decades, product designers have used various methods of path finding to determine optimum solutions for the design and manufacture of ... »
