WebSiGe Heterojunction Bipolar Transistors - Volume 220 WebIn an attempt to maximize the efficiency by improving the properties, SiGe alloys with varying Germanium concentration are fabricated. It is necessary to consider the parameters of Heterojunction Bipolar Transistors (HBT) and demonstrate their improvements due to Ge addition. This paper discusses the important parameters associated with SiGe HBT. Webpoly SiGe heterojunction bipolar transistor (HBT) [8]. The peak cutoff frequencies at V are 20, 26, and 45 GHz, respectively, while typical values are 27, 47, and 65 GHz, respectively. In the case of the first two technologies, which do not feature trench isolation, is a function of emitter length and decreases for shrinking emitter early game mining setup
