    • A computer system for designing a low leakage monotonic CMOS logic circuit. The system performing the computer implements steps of: (a) specifying a reference PFET having its threshold voltage and its gate dielectric thickness and a reference NFET having its threshold voltage and its gate dielectric thickness; (b) synthesizing a schematic circuit design with standard design elements, the standard design elements including one or more reference PFETS and one or more reference NFETs; (c) analyzing one or more circuits for logic stages having predominantly high input logic states or predominantly low input logic states; (d) selecting one or more logic stages determined to have predominantly high input logic states or predominantly low input logic states; and (e) replacing the standard design elements of the selected logic stages with reduced current leakage elements.
    • 一种用于设计低泄漏单调CMOS逻辑电路的计算机系统。 执行计算机的系统实现以下步骤:(a)指定具有其阈值电压及其栅介质厚度的参考PFET和具有其阈值电压及其栅介质厚度的参考NFET; (b)用标准设计元件合成示意电路设计,标准设计元件包括一个或多个参考PFET和一个或多个参考NFET; (c)分析具有主要为高输入逻辑状态或主要为低输入逻辑状态的逻辑级的一个或多个电路; (d)选择确定为具有主要高输入逻辑状态或主要为低输入逻辑状态的一个或多个逻辑级; 和(e)用减少的电流泄漏元件代替所选逻辑级的标准设计元件。
