In this paper, a novel low-power pulse-triggered flip-flop (P-FF) design is presented. Pulse- triggered FF (P-FF) has been considered as a popular alternative to the conventional master ?slave based FF in the applications of high speed. In particular, digital designs now-a-days often adopt intensive pipelining techniques and employ many FF-rich Modules. It is also estimated that the power consumption of the clock system, which consists of clock distribution networks and storage elements, is as high as 20%?45% of the total system power. First, the pulse generation control logic, an AND function, is removed from the critical path to facilitate a faster discharge operation. A simple two-transistor AND gate design is used to reduce the circuit complexity. Second, a conditional pulse-enhancement technique is devised to speed up the discharge along the critical path only when needed. As a result, transistor sizes in delay inverter and pulse-generation circuit can be reduced for power saving. The simulations are done using Microwind & DSCH analysis software tools. Our proposed system simulations are done under 50nm technology and the results are compared with other conventional flip-flops. Hence, our proposed system is showing better output than the other flip-flops.
