Output distortion correction amplifier system |
摘要 |
An output distortion correction amplifier system includes an input stage; a current mirror connected to the input stage; an output stage having its input connected to the input stage and a current mirror and its output connected to the input stage; a compensation impedance connected to the input of the output stage; and a distortion correction circuit for directly sensing the distortion voltage across the output stage and providing to the current mirror a current representative of the distortion voltage for delivering to the compensation impedance a correction current to develop a correction voltage at the input of the output stage to nullify the effect of the distortion voltage.
