Topic: Electronic Devices
Gunn Diode operated at a high frequency is a
- A. Negative resistance device
- B. Positive resistance device
- C. High noise device
- D. None of the above
Answer: A. Negative resistance device
Explanation: A Gunn diode is a Transferred Electron Device (TED) that exhibits negative differential resistance in its V-I characteristics when biased appropriately. This negative resistance property is utilized to construct high-frequency microwave oscillators.
