  • Current limit circuit for compensating for output load mismatch of an RF power amplifier
    Patent number: 7642857
    Abstract: An apparatus and method is disclosed for providing control of current consumption of a power amplifier. The power amplifier comprises an output stage for amplifying a RF signal, and the output stage is operably coupled to an output load. The power amplifier further comprises a bias circuit operably coupled to the output stage, wherein the bias circuit is capable of applying a bias voltage to the output stage. The power amplifier still further comprises a limit circuit operably coupled to the bias circuit for detecting an increase in the current of the output stage under an output load mismatch and in response, decreasing the bias voltage applied to the output stage.
    Type: Grant

  • RF power amplifier mirror circuit for sensing current
    Patent number: 7551027
    Abstract: An apparatus and method is disclosed for providing a mirror circuit for detecting a change in current of a RF power amplifier. The mirror circuit includes a voltage operably coupled with the mirror circuit, a bias circuit operably coupled with the mirror circuit, wherein the bias circuit is capable of applying a bias voltage to the mirror circuit, and an output reference signal. The output reference signal is proportional to the change of current in the RF power amplifier.
