BJT Configurations: Characteristics of CB, CE, and CC Modes
Posted by admin on Nov 19, 2025 in Industrial Electronics and Automation Engineering | 0 comments
Common Base (CB) Transistor Configuration
Circuit Description
In the Common Base (CB) configuration, the input is applied between the Emitter (E) and Base (B), and the output is taken between the Collector (C) and Base (B). The Base terminal is common to both the input and output. For active region operation, the emitter-base junction is forward-biased, and the collector-base junction is reverse-biased.
