Small-signal and noise two-dimensional modeling of submicrometer high speed bipolar transistor

摘要

In the first part of the paper, the Y ma­trix representation is used to directly and accurately extract all the parameters of the --hybrid model. In the second part the noise sources are added to the equivalent model and the analytical expression of noise figure is obtained. This expression is used to get a full set of noise parameters to characterize the behaviour of the bipolar microwave transistors from numerical simulation.
