Description
Summary: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 configuration delivers a very low input resistance, which is mandatory for current-mode applications. Previous reported current comparators present a high-speed response; nevertheless, only few are suitable for low-voltage applications. Simulations and experimental results of a fabricated prototype using the complementary MOS 0.35-μm technology are presented to demonstrate the circuit feasibility.
