Noise Model

The equivalent noise current source is used for thermal noise in ohmic resistance:

Shot noise is assumed for transfer current

Shot noise for current across BE junction is taken into account in the following equation

A flicker noise source is implemented for the BE junction

Other Effects

Self-heating is included to overcome one of the most significant deficiencies of the SGPM for advanced processes including III-V HBTs.
