Integrated low-voltage converter architecture with ac power delivery

Future computation systems pose a major challenge in energy delivery that is difficult to meet with existing devices and design strategies. To reduce interconnect bottlenecks and enable more flexible computation and energy utilization, it is desired to deliver power across the interconnect to the chip at high voltage and low current with on- or over-die transformation to low voltage and high current. This paper presents an integrated converter architecture with ac voltage transformation to provide very-high-frequency, low-voltage integrated power delivery.
