  • Active clamping circuit for power amplifiers
    Patent number: 6580321
    Abstract: An active clamping circuit for a multi-stage power amplifier includes a feedback circuit which affects the gain of the amplifier. The feedback circuit feeds an output via a filter and a clamping transistor to an input of at least one stage of the power amplifier.
