摘要
This work presents a 3D-integrated voltage regulator which leverages a distributed current-balancing control scheme to power a 50A compute domain. The voltage regulator operates with a frequency of 90MHz leveraging 4 phases of 3nH package-embedded inductors per Fully Integrated Voltage Regulator (FIVR) instance.
