“…In the deep-submicron era, the contribution of the static power to total power consumption is significantly increasing [49,87]. Therefore, several techniques for reducing static power consumption have been proposed over the past few years [1,2,7,28,33,37,41,42,46,58,60,61,73,80,91,93,95,105,107]. In this section, we briefly explain power-Gating and voltage-scaling, two widely used techniques shown to be effective at reducing static power.…”
