Kroemer in the 1970s [2], the technology did not become available until the 1980s. A tremendous development has taken place since then and the heterojunction bipolar transistor (HBT) has become an ...

In this module on BJTs (bipolar junction transistors), we will cover the following topics: BJT Device structures, Energy band diagrams, Active bias, Leakage current, Recombination in base, Hoe ...
