Research on low power design in SOC by using charge-recovery technology

Because of the function and complication of SOC ceaseless increasing, low power design in SOC is becoming more and more important. On the base of the voltage scaling technology for decreasing power of SOC, and making use of the advantage of charge-recovery technology to reduce power efficiently, this paper presents an improved adaptive voltage scaling method(IAVS),which combines the system design and the circuit design in SOC. The IAVS conquers the disadvantage of charge-recovery circuits, which need multi-pulse electrical source and it will efficiently decrease the system power dissipation.
