Circuit design and power supplies
Type
A
Common collector
B
Common gate
C
Common emitter
D
Common base
Answer Notes
The alpha of a bipolar junction transistor is specifically defined for the common base configuration. In this setup, the base terminal is shared between the input (emitter) and output (collector) circuits.
Alpha measures the ratio of the output current (collector current) to the input current (emitter current). By contrast, beta is specified for the common emitter configuration, and common gate applies to field-effect transistors (FETs), not bipolar transistors.
