Abstract:

Hierarchical power distribution using a power tree is developed. It supports fine-grained power gating with dozens of power domains like fine-grained clock gating and effectively reduces leakage currents for 1-million-gate power domains to 1/4000 in multi-CPU processors with minimal area overhead. This paper demonstrates the integration of 20 power domains in a 90nm single-chip 3G cellular phone processor
