Abstract
In chapter 3 the silicon-germanium technology used throughout this work is presented. First, different large-signal models and operating points of a bipolar transistor are explained. Additionally, a small-signal model in the active forward region with the resulting small-signal parameters is introduced. The influence of parasitic elements on the performance of bipolar transistors in the millimeter-wave region is analytically described. In the following advantages of the heterostructure principle of a SiGe HBT are given. The structure of the SiGe process from Infineon Technologies is explained different available transistor types with their respective speeds and breakdown voltages are introduced. Furthermore, the scaling technique for a high-performance technology that is partially in used this work is presented. At the end of the chapter different available passive devices as well as their models are presented and the implementation of microstrip lines is explained.
