摘要
本文提出了一种更加有效的待机模式功耗优化方案,一方面进行更加精细的电源控制,尽可能多的切断待机模式的漏电来源;另一方面从电路级优化关断模式下的核心模块-电源控制模块,采用组合逻辑以简化电路,进一步降低功耗.后仿真结果显示,关断模式下的电源控制模块的静态漏电流仅为18.87pA,关断模式总静态电流为20.8nA,并具有较短的状态转换时间.
In this paper, we optimize the supply control in off-mode and meanwhile, simplify the circuit of the supply control unit, which is the core module under off-mode, by using combinational logle circuit to reduce power dissipation. The post-layout simulation shows that the leakage current of supply control unit under off-mode is only 18. 87 pA, and a relatively short mode switching time is also achieved.
