Question

(A) Tunnel diode is a heavily doped pn junction diode that exhibits negative differential resistance.
(B) Stability factor (S) is the maximum for a voltage divider bias circuit.
(C) The operational amplifier works as a comparator circuit in open loop configuration.
(D) Biasing is done to set the quiescent point of the transistor in the middle of the DC load line.
Choose the correct statements from the options given below:

• A. (A), (C) and (D) only
• B. (A), (B) and (C) only
• C. (A), (B), (C) and (D)
• D. (B), (C) and (D) only

Hint:

Tunnel diodes are special due to their ability to exhibit negative differential resistance.

Answer 1

The Correct Option is C

All statements about tunnel diodes, stability factor, operational amplifier, and biasing are correct.
Hence, all are true.
Final Answer: \[ \boxed{(3)} \]
