摘要：
A gain control amplifier provides amplitude variation of an input signal that is coupled to the amplifier, by adding or combining a higher frequency signal that overdrives or distorts the amplifier to one or more degree(s), to provide the gain variation of the input signal. A predistortion circuit may be included to further reduce distortion of the input signal at the output of the amplifier.
