Automatic gain control circuit

Image Number 12 for United States Patent #6608524.

In a state where a PLL circuit is not locked, a gain control signal according to the difference between a peak value of a reproduced signal and the upper or lower limit value of the dynamic range of an A/D converter is given to a variable gain amplifier. In a state where the PLL circuit is locked, a gain control signal according to the difference between the reproduced signal and a reference value that corresponds to a level to which the reproduced signal belongs is given to the variable gain amplifier for each sampling point of the A/D converter. The variable gain amplifier amplifies the reproduced signal with a gain according to the gain control signal.
