Abstract :
The vertical bipolar intercompany (VBIC) model has been applied to silicon-germanium heterojunction bipolar transistors (SiGe HBTs). The model includes the improved Early effect, quasi-saturation, substrate parasitic, avalanche multiplication, and self-heating. Several device parameters have been extracted from SiGe HBTs and implemented in the VBIC model. A comparison is made with the SPICE Gummel-Poon model. The usefulness and accuracy of the VBIC model for SiGe HBTs are demonstrated by way of comparison of simulated and measured room temperature device data
