Abstract :
The stability of a microwave amplifier is reported in this paper. The presence of a generation-recombination noise source is investigated both in the frequency and time domains. An analytical expression of the Allan variance in the case of Lorentzian noise is originally determined in the time domain and agrees with previous work. The model is supported by experimental data realized at different temperatures which corroborates the presence of a thermally activated process.
