ABSTRACT:
A digital amplification device has a digital amplifying unit, a low-pass filter for integrating a digital signal, and a current feedback circuit that is transformer-coupled to the low-pass filter and feeds back current to the differential input terminal. A signal related to distortion is fed back and the distortion is reduced.
