Design of power delivery networks for noise suppression and isolation using power transmission lines
In conventional design of power delivery networks (PDNs), the PDN impedance is required to be less than the target impedance over the frequency range of interest to minimize the IR drop and to suppress the inductive noise during data transitions. As a result, most PDNs in high-speed systems consist …

Improving data center power delivery efficiency and power density with differential power processing and multilevel power converters
Existing data center power delivery architectures consist of many cascaded power conversion stages. The system-level power delivery efficiency decreases each time the requisite power is processed through the individual stages, and the total power converter footprint increases by each cascaded …
