A Novel Approach to HF-Noise Characterization of Heterojunction Bipolar Transistors
We present a numerical HF noise analysis of Si/Si1-xGex/Si heterojunction bipolar transistors based on the time-dependent solution of the drift-diffusion equations. For the MHz range an analytical expression for the noise figures is derived.
