Abstract :
An overview on the compact modeling activities within the DOTSEVEN project is given. Issues such as geometry scaling, substrate coupling and thermal effects as well as HICUM Level 2 features enabling the accurate modeling of the linear and non-linear characteristics of the latest generation of SiGe HBTs are discussed. Furthermore, experimental results for the most important DC and small-signal characteristics as well as selected examples for non-linear modeling of the most advanced SiGe HBTs from two different technologies are presented. Model verification issues related to limited on-wafer high-frequency measurement capability and the accurate calibration at multi-hundred GHz are briefly touched.
