Comparative analysis of low power master slave single edge triggered flip flops lmran ahmed khan and mirza tariq beg department of electronics and communication, jamia millia islamia, new delhi, india abstract: in this paper, we compared various previously published master slave single edge triggered d flip. In the research of low power and low voltage vlsi circuits, the use and implementation of dual edge triggered flip-flop (detff) has gained more attention at the gate level de- sign the main advantage of using detff is that it allows one to maintain a constant throughput while operating at only half the clock frequency.
Ultra-low-power pulse-triggered flip flop is designed and simulated by reducing the number of transistors stacked along the remains high, node x will be discharged on every rising edge of the clock this leads to a sccer is known as the single ended conditional capturing energy recovery p-ff shown in figure 23 [7. Abstract: the paper presents new low-power flip-flops which are faster compared to previously proposed structures the single-edge-triggered flip-flop, called the mhlff (modified hybrid latch flip-flop), reduces the power dissipation of the hlff (hybrid latch flip-flop) by avoiding unnecessary node transitions to reduce the. In this approach flip-flopsamples data on both rising and falling edges of the clock so that only half the clock frequency is needed to obtain the same data throughput as compared to that of single edge triggered flip-flops (setffs)  several low power, high speed dual-edge triggered flip flop designs have been studied.
Reduces the above two stages into one stage and is characterized by the soft edge property and a negative setup time, resulting in small d-q delay in this paper, a new high performance, low power, low d to q delay and with average power pulse triggered flip-flop is devised the proposed pulse edge triggered flip -flop is. Low-power single- and double-edge-triggered flip-flops for high-speed applications abstract: the paper presents new low-power flip-flops which are faster compared to previously proposed structures the single-edge-triggered flip -flop, called the mhlff (modified hybrid latch flip-flop), reduces the power dissipation of the. Optimization of cmos low power high speed dual edge triggered flip flop harpreet singh abstract: in recent years, there has been an increasing demand for high-speed digital circuits at low power consumption the use of dual edge-triggered flip-flops can help reduce the clock frequency to half of the single.

The previous flip-flops dual edge-triggered flip flops are becoming a popular technique for low-power designs since they need halving of the clock frequency a double edge-triggered flip flop can be designed by two transparent latches in parallel whereas single-edge triggered flip flop in series dual-edge triggered flip -flop. In this paper it is proposed to implement low-power shift register using double edge triggered flip-flops and make comparison analysis of existing double edge as we know, the clock system which consists of the clock distribution network and timing elements(flip-flops and latches) is one of the most power consuming.
