Reducing leakage consumption is one of the major design goals. Domino logic circuits are applied extensively in high-performance integrated circuits. A circuit technique for mitigating NBTI-induced degradation and reduce standby leakage current is presented in this paper. Two transistors are added to the standard domino circuit to pull both the dynamic node and the output up to VDo, which puts both the keeper and the inverter pMOS transistor into recovery mode in standby mode. Due to the stack effect, leakage current is reduced by the all-0 input vector and the added transistors. Experimental results reveal up to 33% NBTI-induced degradation reduction and up to 79% leakage current reduction.展开更多
