In this paper, the authors present a low-power Flip-Flop (FF) design featuring an explicit type pulse-triggered structure and a modified true single phase clock latch based on a signal feed-through scheme. The proposed design successfully solves the long discharging path problem in conventional explicit type Pulse-triggered FF (P-FF) designs and achieves better speed and power performance. Based on post-layout simulation results using TSMC CMOS 90-nm technology, the proposed design out-performs the conventional P-FF design Data-Close-to-Output (DCO) by 8.2% in data-to-Q delay.
