Abstract :
We present the results of the 2D numerical simulation of a silicon permeable base transistor. We correlate the slight degradations of the transconductance and transit frequency, as well as the large improvement of the power capability which were obtained with a non-uniform doping profile, to the physical mechanisms involved, and showed that a significant net improvement of the fTVB product can be gained by this means.
