| 摘 要： | 逐次逼近型模数转换器由于性能折衷而得到了广泛的应用。其中，比较器和数模转换器的精度和速度极大地限制了整个系统的性能。因此，具有失配校准功能的比较器是逐次逼近型模数转换器的关键。设计了10bit逐次逼近型模数转换器中的比较器，对比较器的电路结构和工作原理有较详细的论述。

| Abstract: | The successive - approximation analog - to - digital converter is widely used because of its eclectic capabilities. In this kind of converter, the speed and precision of comparator and digital - to -analog converter greatly affect the performance of the whole system. Therefore, the design of comparator with offset cancellation technology is the key to the SAB ADC. A eomperator used in a 10 - bit SAR ADC is designed and presented in this paper. The author describes the architecture of this comperator in detail. |
