Full text linkInvited PaperTemperature dependence of SiGe HBT static and dynamic characteristics
No full textThe SiGe HBT is a good candidate for MIC, MMIC and high speed logic circuits below 50GHz at ambient temperature and also at cryogenic temperature. A static and dynamic analysis of abrupt junction SiGe HBTs is presented in a wide range of temperatures, biases and frequencies up to 50GHz. The different transit times are investigated by analyzing the temperature dependence of the devices'static and HF properties between 50K and 300K
