High-speed dynamic logic styles for scaled-down CMOS and MTCMOS technologies

Abstract

A new high-speed domino circuit, called HS-Domino is developed. HS-Domino resolves the trade-off between performance and noise margins in conventional CD-Domino logic while dissipating low dynamic power with minimal area overhead. A dual-threshold (MTCMOS) implementation of HS-Domino and DDCVS logic is also devised. This implementation achieves low leakage values during standby, while maintaining high performance and low dynamic power during the active mode.
