摘要:
本文报告了 28nm 全耗尽 SOI CMOS 技术的首次低温特性表征。文中对从室温到液氦温度范围内的数字/模拟性能以及体偏置进行了全面研究。尽管处于低温工作状态,体偏置的有效性保持不变,并提供了优异的 $V_{TH}$ 可控性。低温工作可实现更高的驱动电流和大幅降低的亚阈值摆幅(低至 7mV/dec)。FDSOI 可为低温低功耗电子器件提供一种有价值的方法。展望了诸如量子处理器的经典控制硬件等应用。
英文摘要:
This paper reports the first cryogenic characterization of 28nm Fully-Depleted-SOI CMOS technology. A comprehensive study of digital/analog performances and body-biasing from room to the liquid helium temperature is presented. Despite a cryogenic operation, effectiveness of body-biasing remains unchanged and provides an excellent $V_{TH}$ controllability. Low-temperature operation enables higher drive current and a largely reduced subthreshold swing (down to 7mV/dec). FDSOI can provide a valuable approach to cryogenic low-power electronics. Applications such as classical control hardware for quantum processors are envisioned.
