Abstract
An input distortion correction current-feedback amplifier system includes a current mirror; an input stage connected to the input of the current mirror; an output stage connected to the output of the current mirror; a feedback circuit connected from the output stage to the input stage; a compensation impedance connected to the output of the current mirror; and a distortion correction circuit for sensing the distortion voltage across the input 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.
