Comments on "New single-clock CMOS latches and flip-flops with improved speed and power savings"

Abstract

For original paper see J. Yuan and C. Svensson, ibid., vol.32, pp.62-69 (1997). In a recent paper, Yuan and Svensson propose various single-clock differential flip-flops; however, those using a dynamic slave are unsafe in the presence of input glitches. Further, a double-edge triggered flip-flop is developed from one of the semistatic versions.
