蕴涵门(IMPLY gate)的电路符号

蕴涵门[1](英语:Implies gate,简称IMPLY gate[2]是数字逻辑电路中的一种逻辑门,主要用来完成布尔代数实质条件、实质蕴涵或蕴涵算子。

蕴涵门可由CMOS或其他晶体管设计,利用如下公式:

另外蕴涵门也可以由忆阻器组成,且只需要由两个忆阻器即可组成[3][4],由于布尔代数的特性可使其他布尔函数化成由逻辑蕴含表示[5],因此利用蕴涵门与忆阻器来设计晶体管可以大幅缩小体积[6]

两个忆阻器即可完成一个蕴涵门[7][8]

如果B为逻辑真, 无论A为任何值都会输出逻辑真的信号。
其中,X代表输入的是无论何值皆可。
如果B为逻辑假, 并且A为逻辑假, 才会输出逻辑真的信号。
其余情况则输出逻辑假的信号。
蕴涵门可以用来判断两输入的或是否为第二输入。

使用蕴涵门组合成的与非门

大部分的逻辑门都可以用蕴涵门组合而成,例如与非门可以用两个蕴涵门组合而成[9]

其他逻辑门

蕴含非闸

蕴含非闸,简称NIMPLY gate是数字逻辑电路中实现非蕴涵的一种逻辑门。

这种运作方式的器件已在生物学的逻辑信号中有相关研究。[10]
