ABSTRACT:
An amplifier circuit comprising an input amplifier stage, a push-pull output stage, a bias stage having the same construction as the input amplifier stage, a first resistor to be given a current flowing through the bias stage, second and third resistors connected along with the first resistor between a power supply and the ground in series therewith, and fourth and fifth resistors connected between the output point of the push-pull output stage and the ground in series therewith. The point of connection between the fourth resistor and the fifth resistor is connected to the input amplifier stage to provide a negative feedback loop having no capacitor.
