Abstract
In the present paper we evaluated the fabrication process of AlGaAs/GaAs Heterojunction Bipolar Transistors (HBT’s) by means of low frequency noise characterizations carried out in the 100Hz-100kHz frequency range. We investigated the spectra of the base current fluctuations. The obtained results are compared with the data reported in the literature. The fabrication technology and the experimental set-up are briefly described.
