用电流控制逻辑降低模/数混合集成电路的噪声

Current-control Logic to Lower the Noise of A/D Mixed Integrated Circuit

本文分析了静态CMOS逻辑开关在模/数混合集成电路中的开关特性,噪声特性和功耗及功耗延迟等性能的影响,并用电流控制逻辑结构代替静态CMOS逻辑。

In this article, the author analyses the characteristics of static CMOS logic switch, noise, power dissipation and power dis-sipation delay in A/D mixed integrated circuit. Static cmos logic is replaced by electricity contol logic,so that low voltage performance can be realized and crest value mixed electricity can be reduced about 3 orders of magnitude.
