Abstract
- For recent voltage regulators powering microprocessors, the amount of space they use is the most challenging issue. Moreover, efficient energy management depends not only on heavyload efficiency but also on light-load efficiency. So far, to reduce the space taken near the microprocessor and to increase heavy-load efficiency, a two-stage voltage regulator has been proposed, and the adaptive bus voltage positioning (ABVP) control concept has been proposed to increase the light-load efficiency of the two-stage structure. In this paper, a ABVP control structure is proposed and is employed in the adaptive voltage positioning (AVP) system. For the proper design of this system, the system is modeled and analyzed, and the experimental results verify the analysis. [ABSTRACT FROM AUTHOR]
