Abstract

The paper describes a new figure of merit reachable in terms of very low power dissipation for a 12 bit, 40 MS/s Analog to Digital Converter in a 65 nm CMOS process with 1 V power supply. A differential time interleaved successive approximations register architecture is used. Each individual ADC channel is optimized with regard to power consumption hence interleaving 28 ADC channels in an analog memory like method, the total power consumption is only 280 μW including all the reference voltage drivers, the clock management and the digital sections. The total layout area of this converter is 0.87 mm2.

设计基于时间交错 SAR 架构的超低功耗 12 位 40 MS/s ADC

本文介绍了在 65 纳米 CMOS 工艺中采用 1 V 电源供电的 12 位、40 MS/s 模数转换器在超低功率耗散方面可达到的新性能指标。采用了差分时间交错逐次逼近寄存器架构。每个模数转换器通道的功耗都经过优化，因此采用类似模拟存储器的方法交错处理 28 个模数转换器通道，包括所有基准电压驱动器、时钟管理和数字部分在内的总功耗仅为 280 μW。该转换器的总布局面积为 0.87 平方毫米。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
