How the common collector current gain is obtained?
The common-emitter amplifier configuration has a current gain equal to the β of the transistor, the input current went through the base and the output (load) current went through the collector, and β by definition is the ratio between the collector and base currents. In the common-collector configuration, though, the load is situated in series with the emitter, and thus its current is equal to the emitter current. With the emitter carrying collector current and base current, the load in this type of amplifier has all the current of the collector running through it plus the input current of the base. This yields a current gain of β plus 1.
How to Calculate Common Collector Current Gain?
Common Collector Current Gain calculator uses Common Collector Current Gain = Base Transport Factor+1 to calculate the Common Collector Current Gain, Common Collector Current Gain is defined as the ratio of the emitter current to the base current. Common Collector Current Gain is denoted by Ai symbol.
