NEET Physics Question - Semiconductor Physics - P-N Junction Diode and its applications

Assertion (A): The logic gate NOT can not be built using diode.

Reason (R): The output voltage and the input voltage of the diode does not have \(180^{\circ}\) phase difference.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is true because a NOT gate requires active components to provide inversion and gain, which a passive diode cannot do. Reason (R) is true because a diode circuit does not inherently provide the \(180^{\circ}\) phase shift characteristic of logic inversion. Thus, (R) correctly explains (A).
