Abstract :
Recent progress in the development of subthreshold circuit design techniques has created the opportunity for dramatic energy reductions in many applications. However, energy efficiency comes at the price of timing and energy variability due to process variations. We explore energy optimality in the subthreshold regime, discuss variability in this region, and highlight the energy and variability characteristics of a real subthreshold design
