ABSTRACT:
The distortion of an emitter-follower output stage of a video amplifier for driving a cathode of a picture display tube can be reduced without rendering a beam current control via this output stage impossible, by using a low-distortion buffer stage for producing a negative feedback signal at the output of the output stage. A higher follow rate for small signal variations can be obtained with the aid of a bias current or quiescent current which then is subtracted again from the current applied to an input of a beam measuring circuit which is controlled by the output stage.
