Abstract
This paper proposes new SOI circuit strategies for simultaneous reduction of standby gate and sub-threshold leakages. Various enhanced MTCMOS design alternatives are analyzed. A new method for assigning the V/sub TH/ and sizes of header and footer transistors is proposed, and stacking of headers/footers is analyzed. The optimum stacking height and tapering/sizing ratio under various design constraints are determined. Our strategies reduce MTCMOS standby leakage further by as much as 20/spl times/ and reduce virtual supply noise by 15%.
