Power gating in wireless sensor networks

In this paper we investigate power-saving techniques that employ the on-chip power gating to reduce the static power loss. Gating the power of single functional blocks in a wireless sensor node with help of a power management unit and power gates, we minimize the static power loss in a wireless sensor network. The proposed power gating approach is implemented and verified on test architecture. The measurement results show that the static power loss of gated functional blocks is eliminated.
