ABSTRACT:
Volume control circuits generally vary the overall gain of a low-frequency amplifier by varying the gain in a negative-feedback branch. At very high gain, at which very large output signals are obtained, the negative-feedback is then very small, which may produce a non-linear distortion. In accordance with the invention the gain of a frequency-compensation stage is varied so that it increases when the overall gain increases. The loop gain at higher output amplitudes is now higher than it would otherwise be so that non-linear distortion is reduced.
