With CMOS device dimensions falling below 100 nm, achieving higher performance and packing plex functionalities into digital integrated circuits have e easier. However, the scaling trend poses new challenges to design and process engineers. Such challenges include larger process parameter variations and the consequent parametric yield loss, ensuring the reliability of deep sub-micron technologies under soft errors, and reliably fabricating billions of devices ona die. The objective of my research has been to develop circuit and system level techniques to address process variations, transient errors, and the reliability concerns in deeply scaled CMOS technologies. The proposed techniques can be divided into three parts, highlighted in the next three sections. The first part addresses the issues related to process variations and proposes techniques to reduce the variation effects on power and performance. The second part proposes a novel low-overhead defect-tolerant approach for CMOS designs capable of efficiently recovering from dozens of d
