本文讨论了一种针对低功耗传感应用的异步模数转换器的设计。异步采样方案只在输入信号发生变化时进行采样，从而节省了功耗。介绍了采用自适应分辨率提高ADC最大输入频率的思想。以0.18 μ m CMOS工艺制作了原型芯片。给出了初步测量结果。
This paper discusses the design of an asynchronous analog-to-digital converter targeted for low-power sensing applications. The asynchronous sampling scheme will save power because it only samples the input signal when it is changing. The idea of using an adaptive resolution to increase the maximum input frequency of the ADC is introduced. A prototype chip has been fabricated in a 0.18 mum CMOS process. Initial measurement results are presented.
