Modelling and Near-Threshold Computing of Power-Gating Adiabatic Logic Circuits

This paper introduces a power-gating scheme appropriate for near-threshold operating of single-phase adiabatic circuits. A transmission gate with MOS bootstrapping scheme is used as the power-gating switch, which is used to reduce energy overhead. CAL (Clocked Adiabatic Logic) circuits are investigated. The analytical model for power-gating adiabatic circuits is constructed, and the energy overhead of the proposed powergating scheme is analyzed in detail. The results show that the proposed power-gating technique is suitable for near-threshold operating.

W artykule wprowadzono schemat bramkowania mocy dla progowej operacji jednofazowych obwodów adiabatycznych. Zaproponowano model analityczny bazujący na układach MOS jako przełącznikach bramkujących.
