N2 - On-chip switched-capacitor (SC) DC-DC converters have recently been demonstrated in silicon for high-performance applications such as multicore processors. The efficiency of the power delivery system using SC converters is a major concern, but this has not been addressed at the system level in prior research. This work develops models for the efficiency of such a system as a function of size and layout of the SC converters, and proposes an approach to optimize the size and layout of the SC converter to minimize power loss. The efficiency of these techniques is demonstrated on both homogenous and heterogenous multicore chips.
