Abstract:
A multiple power domain strategy in which each power domain has an independent power gating structure is an effective means for reducing leakage power consumption in a system-on-a-chip. During an individual power gating structure power-mode transition, however, serious inductive noise is introduced that may affect normal operation of neighboring circuits. We present a novel power gating structure in which inductive noise is reduced through gradual turn-on and turn-off its sleep transistor. Experimental simulation results with PowerSpice fixtured in different package models demonstrate the effectiveness of the proposed power gate switching noise reduction technique.
