Q. |
The mode of operation in which the Gunn diode is not stable is: |
A. | gunn oscillation mode |
B. | limited space charge accumulation mode |
C. | stable amplification mode |
D. | bias circuit oscillation mode |
Answer» A. gunn oscillation mode | |
Explanation: in gunn oscillation mode, the device is unstable due to the formation of accumulation layer and field domain. this high field domain moves from cathode to anode. |
