Control and Stability Analysis for the Vdd-hopping Mechanism

Abstract : In low-power electronics, achieving a high energy efficiency has great relevance. Nowadays, Global Asynchronous Local Synchronous Systems enables to use a Local Dynamic Voltage Scaling architecture. This technique allows to reach a high energy efficiency. Moreover, Local Dynamic Voltage Scaling can be implemented using different approaches. One of them is the Vdd-Hopping technique. In this paper, we propose an innovative control approach which aims for minimizing the energy dissipated during the Vdd-Hopping transients. In addition, our control also includes the ability to limit the current peaks during such transients. Stability of the closed-loop system is analyzed. A discrete version of this controller is obtained, which coincides with ENergy-AwaRe Control (ENARC) that is patent pending. And a comparison of this last one with another published is done.
