Low power and high speed Data-dependent Precharge Suppression DFF

저전력, 고속데이터 의존 프리차지 억제 DFF

This paper presents a data-dependent precharge suppression(DPS) D-flip-flop(DFF) with precharge suppression scheme according to data-transition probability The main feature of the DPS DFF is that precharge is suppressed when there is no data transition. The proposed DPS DFF consumes less power than the conventional Yuan-Svensson's true single phase clocking(TSPC) DFF when the data-transition probability is low. The simulation result shows that the power consumption is reduced by 42.2 % when the data-transition probability is 30%.
