WebDec 18, 2009 · Practical emitter-follower circuits provide a voltage gain that is slightly less than unity. The precise gain that determines the resistor amplification factor, or A R of the circuit is: A R = 1/ (1 - A V ). For example, if circuit gain is 0.995 (as in Fig. 13), then A R is 200 and the R3 impedance is almost 10 megohms. WebFollowing equation is used to calculate overall current gain of the Darlington pair. Followng equation is used to calculate collector current from base current and vice versa provided current gains of both individual transistors are available.
