A novel topology for modular frequency dividers with

In this paper, we introduce a new topology for modular frequency dividers which improves the speed and decreases the power consumption in true-single-phase-clock (TSPC) based dividers and enhances the speed in their Extended-TSPC (E-TSPC) based counterparts. Two dividers are designed in 0.18 µm TSMC CMOS technology with 1.8 V …
