Abstract

The energy consumption in notebooks and multimedia terminals limits autonomy, high performance and further reduction of size. The DVS represents an alternative solution to current techniques that dramatically reduces energy consumption in digital systems. The power supply becomes a very important part of the system as it enables the voltage scaling. This paper analyzes the requirements and challenges for these power supplies, highlighting the interesting solutions and the research trends.
