Popis: | High-performance many-core processors and GPUs demand 100s of Watts of power in a single voltage/power domain on chip, operating below 1V. High-frequency and highcurrent-density fully integrated voltage regulators (FIVRs) with in-package air core inductors (ACIs) [1] or on-package magnetic inductors can deliver power with high efficiency and low distribution losses in compact footprints. Multiple FIVR tiles must be “ganged” to support the large on-chip voltage/power domains while meeting the reliability constraints of the active and passive elements, and maintaining high overall efficiency. |
