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. sharepoint form vs powerapps form
