Because the emitter is grounded, even if sometimes via a resistor, this transistor configuration is referred to as a Common Emitter amplifier. In this circuit if you were to start with the ...

The base forms the input and its bias circuit is identical to that of ... taken a look at the three basic configurations of a transistor amplifier, as well as the fundamentals of biasing a bipolar ...

to develop high-electron mobility transistors (HEMTs) and amplifier circuits for highly efficient satellite communication based on the wide-bandgap compound semiconductor gallium nitride (GaN).
