Question

Answer 1

3.1.

3.1.1)

P-n junction diode:

D. It has heavily doped p-type and n-type regions separated by an intrinsic region.

3.1.2)

Varactor diode:

A. Its operation depends on the capacitance that exist at the p-n junction which is reverse biased.

3.1.3)

Tunnel diode:

C. It has a negative resistance region where an increase in terminal voltage results in reduction in the diode current.

3.1.4)

Zener diode:

B. It permits the current to flow in the forward bias direction but it will also flow in the reverse bias when  the voltage is above the breakdown voltage.

Solution:

3.1.1) P-n junction diode: D.

3.1.2) Varactor diode: A.

3.1.3) Tunnel diode: C.

3.1.4) Zener diode: B.
