Physics - Semiconductors Question with Solution | TestHub

(A) is a NAND gate so output is $\overline{1\times 1}=\overline{1}=0$ (B) is a NOR gate so output is $\overline{0+1}=\overline{1}=0$ (C) is a NAND gate so output is $\overline{0\times 1}=\overline{0}=1$ (D) is a XOR gate so output is $0\oplus 0=0$
