ABSTRACT:
A push-pull amplifier consisting of a complementary pair of output transistors whose bases are interconnected by a resistor. According to the invention, the bases are separately connected to the outputs of two current mirrors whose inputs are interconnected via a second resistor. A relation is then obtained between the values of the two resistors for which the quiescent current through the output transistors is supply-voltage independent in a first-order approximation.
