Abstract:Abstract:The increasing popularity of DVFS (dynamic voltage frequency scaling) schemes for portable low power applications demands highly efficient on-chip DC-DC converters. The primary aim of this work is to enable increased efficiency of on-chip DC-DC conversion for near-threshold operation of multicore chips. The idea is to supply nominal (high) off-chip voltage to the cores which are then "voltage-stacked" to generate the near-threshold (low) voltages based on Kirchhoff's voltage law through charge recycli… Show more
