Creating Output Buffer Circuits by Karnaugh Maps

Output buffer circuits are often adopted for driving next stage Integrated Circuit (IC). Most Input/ Output (I/O) circuit designers use the output buffer circuits, but cannot majorly modify the circuits. In this study, output buffer circuits are derived from Karnaugh maps so I/O designers can use only one pen and one paper to draw output buffer circuits. They don’t need to look at any existed circuits, but just realize output design principals. Then, they can easily create output buffer circuits.
