The output current is converted into a voltage signal whose amplitude is detected after filtering the voltage signal by a low-pass filter. Therefore, a reference signal corresponding to the input data is generated and its amplitude is detected. We have a modulator for generating a modulation current, it regulates the amplitude of the modulation current, according to the difference between the two detected amplitudes.} }
