New Data Selector Based on Current-mode CMOS Circuit

基于阈算术代数系统的CMOS电路设计技术和方法,根据任意二值三变量函数的最小项规范展开表示,通过和图分解,分别设计实现了8个最小项表达式,进一步组合8个子电路,提出一种新型电流型CMOS数据选择器.Hspice模拟表明该数据选择器具有正确的逻辑功能和良好的瞬态特性,且功耗低、速度快.

Basing on the CMOS circuit design technique and method of threshold arithmetic algebra system,this paper develops and represents the minimum term specification of arbitrary binary trivariate function,and uses the method of graph decomposition to design and implement 8 minimum term expressions respectively.It further designs eight sub-circuits to implement a new current-type CMOS-based data selector.The Hspice simulation shows that the data selector has the correct logic function and good transient characteristics,and the power consumption is low and the speed is fast.
