Examples
2-1 OAI-gate
A 2-1-OAI gate realizes the function
with the truth table shown below.
2-2 OAI gate
A 2-2-OAI gate realizes the function
with the truth table shown below.
Realization
OAI-gates can efficiently be implemented as complex gates. An example of a 3-1 OAI-gate is shown in the figure below.
Examples of use
One possibility of implementing an XOR gate is by using a 2-2-OAI-gate with non-inverted and inverted inputs.
