| 摘 要： | 亚阈值数字电路技术是特殊的超低功耗技术,适用于对低功耗要求苛刻,但速度要求不高的应用领域。该文提出了亚阈值数字标准单元设计方法,从尺寸、驱动、结构几方面设计了亚阈值数字标准单元库。一个采用亚阈值单元库设计的32位数据通路结果表明:与采用传统库相比,数据通路的噪声容限提高了8%,工作频率提高了42%,能耗降低了27%,能量延迟积降低了49%,漏电流降低了64%。

| Abstract: | Sub-threshold digital circuits is an ultra-low power technology for applications that do not require high speed.This paper provides circuit design methods for sub-threshold standard cells including size,drive capability,and structure for a sub-threshold digital standard library.Simulations of a 32-bit data-path designed using the sub-threshold cells show that the noise margin of the new data-path is improved by 8%,the frequency by 42%,the energy consumption by 27%,the Energy-Delay Product(EDP) by 49% and th... |
