摘　　要：数字比较器是数字系统的基本单元之一。传统的数字比较器采用门级设计技术,电路结构不规则,不利于大规模集成电路的设计。在研究传统数字比较器的基础上,提出了一种基于CMOS传输门的开关级数字比较器电路。研究表明,和传统的数字比较器相比,这种电路具有结构简单,布局规则,运算速度快等优点,适用于大规模集成数字比较器的设计,具有一定的研究和实用价值。Magnitude comparator is one of the elements used in digital system. The traditional magnitude comparator is based on gate - level techniques and not suitable for VLSI design. A new type of magnitude circuit in CMOS switch- level is present based on the study of the traditional one. The result shows that it is more simple, regular in layout and faster than the traditional one. It is suitable for the design of VLSI, and has some study and impractical value.
