Almost all power-gating circuits used in MOS current-mode circuits were realized with dual-rail schemes. In this paper, a power-gating scheme for Single-Rail MOS Current Mode Logic (SRMCML) is presented. The modeling of the sleep transistor in power-gating circuits is constructed and analyzed. The optimization methods for sizing sleep transistors of power-gating circuits are addressed in terms of energy dissipations. The design methods of the power-gating SRMCML circuits are presented. The effectiveness of the proposed power-gating structure is verified by using HSPICE simulations with a SMIC 130nm technology.
