A New Area and Power Efficient Single Edge Triggered Flip-Flop Structure for Low Data Activity and High Frequency Applications
Imran Ahmed Khan*, Mirza Tariq Beg Department of Electronics and Communication, Jamia Millia Islamia, New Delhi, India *Email address of Corresponding author: imran.vlsi@gmail.com Abstract In this work, a new area and power efficient single edge triggered flip-flop has been proposed. The proposed design is compared with six existing flip-flop designs. In the proposed design, the number of transistors is reduced to decrease the area. The number of clocked transistors of the devised flip-flop is also reduced to minimize the power consumption. As compared to the other state of the art single edge triggered flip-flop designs, the newly proposed design is the best energy efficient with the comparable power delay product (PDP) having an improvement of up to 61.53% in view of power consumption. The proposed flip-flop also has the lowest transistor count and the lowest area. The simulation results show that the proposed flip-flop is best suited for low power and low area systems especially for low data activity and high frequency applications. Keywords: PDP, reliability, delay, process node, clock frequency

INTRODUCTION
The latest advances in mobile battery-powered devices such as the Personal Digital Assistant (PDA) and mobile phones have set new goals in digital VLSI design. The portable devices require high speed and low power consumption. So the power dissipation has become a prominent issue [1]. For big circuits implementing complex functionalities like control units, microprocessors, usually a very large number of flip-flops are used. So the flip-flops heavily affect the performance of the entire system. This paper focuses on the minimization of power dissipation in the edge triggered flip-flops.
