Early-Stage Planning of Switched-Capacitor Converters in a Heterogeneous Chip

Early-Stage Planning of Switched-Capacitor Converters in a Heterogeneous Chip

The switched-capacitor converter (SCC) has been widely used for voltage regulation in multicore chips, where energy efficiency is the major concern. However as the overhead to integrate SCCs in a chip is non-negligible, the SCCs could not be overused. Hence in this paper we propose an early stage SC...
