2输入双反相器只用一个非门

Question

How do I make a 2 input dual inverter using only one not gate along with any number of and, or, xor gates?

2 input dual inverter

Answer 1

Using this Truth Table , you can do:

!A = ((A^B)&B) | !(A&B)
!B = ((A^B)&A) | !(A&B)

where ! is NOT, | is OR, & is AND, and ^ is XOR.

See this hand-drawn Circuit Diagram for an implementation. I am sure there exist other possible solutions, but this one seems to work.

Answer 2

2 Input Dual Inverter

Simplest solution I could find so far.
