| 中文摘要: |
| 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. |
| 英文摘要: |
| 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 SAR ADC.A comparator used in a 10-bit SAR ADC is designed and presented in this paper.The author describes the architecture of this comparator in detail. |
