Design Technologies for Energy-Efficient VLSI Systems

Abstract

This project has investigated novel design technologies for energy-efficient VLSI systems. Its primary focus has been on charge-recovery circuits. These circuits achieve higher energy efficiency than their conventional counterparts by steering currents to flow across devices with low voltage drops, while recycling undissipated energy in parasitic capacitors. Previous investigations into charge recovery have resulted in complex circuits and architectures that are impractical for high-speed design. This project has led to the discovery of practical low-complexity charge-recovery circuits which achieve high energy efficiency and achieve clock frequencies in excess of 1GHz. The results of this research have been validated through silicon prototyping and experimentation. For four of the inventions resulting from this project, the University of Michigan has filed utility and provisional patent applications with the US Patent and Trademark Office.
