Abstract
An automatic-gain control circuit includes a variable-gain amplifier, a peak-detecting circuit, and an adjustable charge/discharge circuit. The variable-gain amplifier receives an input signal and adjusts the input signal based on a gain-factor control signal for generating a corresponding output signal. The peak-detecting circuit is coupled to the variable-gain amplifier for generating a comparing signal according to a reference signal and the output signal. The adjustable charge/discharge circuit is coupled to the peak-detecting circuit and the variable-gain amplifier for outputting a charge current or a discharge current based on the comparing signal, thereby generating the gain-factor control signal. The ratio between the charge current and the discharge current is adjustable.
