Anomalous Low-Frequency Noise Increase at the Onset of Oscillations in Gunn Diodes

In this work, the presence of anomalous lowfrequency noise effects in Gunn diodes has been studied and evidenced. Near the onset of Gunn instability, there is a limited range of bias voltages for which the noise significantly increases at frequencies well below the frequency of oscillation. For high...

Sumario:In this work, the presence of anomalous lowfrequency noise effects in Gunn diodes has been studied and evidenced. Near the onset of Gunn instability, there is a limited range of bias voltages for which the noise significantly increases at frequencies well below the frequency of oscillation. For higher bias voltages, the oscillation becomes purer and such low-frequency noise drastically vanishes.
