Abstract—
Sub-threshold leakage power is soon expected to dominate the total power consumed by a CMOS circuit in deep submicron ( DSM ) technology. Circuit techniques aimed at lowering leakage currents are therefore highly desirable. In this work, low power CMOS designs using dual threshold voltage ( dual-Vt ) domino logic are proposed. Single threshold voltage ( single-Vt ), standard dual-Vt and modified dual-Vt domino logic circuits regarding power and speed are compared. These design styles are compared by performing detailed transistor-level simulations on bench mark circuits using DSCH3 and Microwind3 CAD tool.
