ABSTRACT:
To actuate a complementary push-pull class B final stage complementary driver transistors are provided whose emitters are electrically interconnected and connected to the collectors of the two final stage transistors via a filter section. This filter section is not integratable into the rest of the circuit on account of the high capacitance value of the capacitor. To permit design of this complementary push-pull class B final stage as an integrated circuit the filter section is replaced according to the invention by a circuit arranged between the emitters of the driver transistors and ground and having dynamic low impedance and being designed such that the operating voltage drops by about half across the integratable circuit.
