Analysis of power dissipation in double edge-triggered flip-flops

摘要

A comprehensive analysis of double edge triggered (DET)nflip-flops' power dissipation, taking into account input signalnstatistics, is presented in this paper. It is shown that using DETninstead of a single edge-triggered flip-flop may result in significantnenergy savings if the input signal has reduced activity. On the othernhand, the high switching rate of DET internal nodes may result in largernpower dissipation if the input signal has a high transition probabilitynor significant glitching
