In which mode can bjt be used for amplifier
Web2 jan. 2024 · β is a ratio between the collector and base currents whereas α is also a ratio but between the collector and emitter currents. There is no special name for α and β as they are both unit-less. However, you may call α as the common-base gain and β as the common-emitter gain. Either way, you will usually see β in the spec sheets of BJT chips.
