An Efficient Design for Reduction of Power Dissipation in Johnson Counter using Clock Gating
Journal Title: International Journal of Science and Research (IJSR) - Year 2015, Vol 4, Issue 1
Abstract
In this paper, a new method for minimizing power dissipation in 4-bit Johnson up-down counter is proposed. In this design, we have used a dual dynamic pulsed flip-flop (DDFF) [1], which supports embedding a logic module (DDFF-ELM) and a power saving technique, namely, clock gating [2] is used. We have used DDFF because it is power efficient compared to other flip-flops in the literature. We have used digital schematic editor (DSCH) for designing; simulation and layout generation is done using Microwind. From the simulation results, it is observed that power dissipation is reduced by 33.9 %.
