Abstract

This article studies the performance of different CMOS comparators. Comparators play an important role in signal processing and other electronic applications. Its speed, energy-efficient and accuracy are largely depending on its noise, kickback and sensitivity. A dynamic bias comparator adds a tail capacitor to store the energy. However, it brings relatively high time delay. A Triple-Tail fully dynamic comparator separates the comparing option into three stages to minimize the resolving time. An improved Triple-latch feed-forward (TLFF) fully dynamic comparator adds extra feed-forward and backward paths to reduce the delay. An innovation Edge-Pursuit Comparator (EPC) adopts a ring structure, allowing two input signals to chase each other and achieves extremely low energy consumption. The dynamic Floating Inverter Amplifier (FIA) comparator combines strongARM latch with the preamplifier stage and achieves high speed and low power consumption. In this article, the parameters and performance of these comparators have been analyzed and compared. Further conclusions are made.
