Abstract: In this paper, a new low-voltage continuous-time current comparator is presented. The main idea is to use the flipped voltage follower as a key element for the comparator input stage. This ...

Abstract: A differential comparator that can sample 40-Gb/s signals and that operates off a single 1.2-V supply was designed and fabricated in 0.11-/spl mu/m standard CMOS technology. It consists of a ...
