Abstract :
The spectra of gate current noise are investigated in GaAs MESFETs between 102 and 104 Hz. A change in the white-noise behaviour is observed with the increase of the gate current. It is shown that the contribution of an ideal Schottky shot noise is associated with two thermal noise components. The thermal noise sources originate in different leakage conductances.
