Sige heterojunction bipolar transistor

SiGe allows CMOS logic to be integrated with heterojunction bipolar transistors, making it suitable for mixed-signal integrated circuits. Heterojunction bipolar transistors have higher forward gain and lower reverse gain than traditional homojunction bipolar transistors. This translates into better low-current and high-frequency performance. Being a heterojunction technology with an adjustable band gap, the SiGe offers the opportunity for more flexible bandgap tuning than silico… 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.
