Considered small signal equivalent circuit, and the model AFC and PFC input stage of a complementary push-pull dc amplifier using bipolar transistors of different conductivity to the outputs of the emitters, followed by cascading. Derived analytical relationships for the AFC and PFC, as the small-signal transfer coefficients of the upper and lower tiers, and the overall small-signal current transfer ratio. Given electrical small signal equivalent circuit format SPICE. It is proved that the mathematical model for the AFC and PFC transfer coefficients obtained by the analysis of circuit transistor cascades and their electrical equivalent circuits, have high convergence.
