| 摘 要： | 为对低功耗电流模互连电路进行快速优化,提出了一种"自顶向下"的动态驱动电流模互连电路的快速优化设计方法.方法首先对动态驱动电流模电路进行行为级建模,并采用MATLAB对数据进行处理优化电路功耗,确定出最优的电流源电流大小.然后利用"2ID/gm"方法,快速而准确地确定出相应MOS管尺寸.同时,也对"2ID/gm"的模拟集成电路设计方法,进行了较为详细的理论分析.仿真结果表明:使用该方法确定出的MOS管尺寸得到的性能十分接近设计指标,只需通过少量修改便可完成设计.该方法大大提高了设计效率.

| Abstract: | In order to optimize the lower power current-mode signaling (CMS) circuit, we offered a top-down methodology to optimize the power of a dynamic overdriving CMS circuit. First, we molded the CMS scheme using a behavioral model-switched current source, which helps us determine the branch current quickly. Under the help of Matlab, we can determine the optimized branch currents, making the average power of the CMS scheme lowest. To get the accurate dimensions of MOSFETs quickly, a new design method of 2ID/gm methodology is introduced. Moreover the detail analysis shows that the 2ID/gm methodology is both practical and scientific. The simulation results using initial values calculated by this methodology are very close to the specs, demonstrating the top-down methodology improving the design efficiency of the dynamic overdriving CMS-circuit. |
