Abstract :
The first quantitative extraction of low-frequency noise equivalent circuit model of self-aligned AlGaAs/GaAs heterojunction bipolar transistor has been performed. It is based on a generalized small signal circuit model including the base and emitter series resistance noise sources. The dominant noise sources are emitter-base current noise source and the resistance noise source. The emitter-collector current noise source is negligible.
