Abstract
This paper presents a design of a high-speed, low-voltage, low power consumption comparator with S-R latch for High speed ADC. The comparator is the most important part in the Flash ADC, since the speed and the resolution is determined by the comparator. In this paper, we do the analysis of the traditional comparator and propose a better structure combing sense amplifier and symmetric S-R latch, which can run faster and provide more stable output signal than the traditional structure. The comparator is composed of a latch based amplifier and a S-R latch which provides stable output. There are many issues in the design of the comparator, we will discuss those design issues in this paper.Keywords
