Current gain common base
WebJan 23, 2015 · In common collector NPN transistor the current gain is defined as the ratio emitter current IE to base current IB. This current gain is represented with γ. γ = IE/IB We know that emitter current IE= IC+ IB γ = (IC+ IB)/IB γ = (IC/IB) + 1 γ = β +1 Hence the relationships between α, β and γ are given as below α = β / (β+1), β = α / (1-α), γ = β +1 WebCommon Base Voltage Gain . The common base circuit is generally only used in single stage amplifier circuits such as microphone pre -amplifier or radio frequency (Rf) amplifiers due to its very good high frequency response. ...
