Question

In the circuit shown in the Figure, $A$ and $B$ are logic inputs and $Y$ is the logic output.

Which of the following logic operations is realized by the circuit?

• A. NOR
• B. OR
• C. XOR
• D. AND

Answer 1

option A

Answer 2

Answer : A

Pmos becomes active for input 0 and nmos becomes active for input 1 ,

A    B    Y
0    0    1
0    1    0
1    0    0
1    1    0

For input A,B as 0,0 then pmos becomes active and drives the vdd to output Y,so the answer becomes Nor logic gate
