Schematic Design Of Transistor Level XOR & XNOR Gate

1.Can you distinguish between AND and XNOR gate when both the inputs are 1?
2. Choose the correct design of A+BC using NMOS only.
3. Choose the correct design of AC+BC using PMOS only.
4. In above question what is the minimum number of transistor required for making the design?
5. Choose the correct design of ABC using complementary logic.
6. Choose the correct design of A+B+C using complementary logic.
7. What will be the minimum number of transistor required for designing ABC+ABC+ABC+ABC
8. What will be the minimum number of transistor required for designing xy+xz+zy+xy+z
9. Reduce the expression xy(z+w)+y(xz+xz)+zw and tell the min number of transistor required for the design.
