  • POWER AMPLIFIER SATURATION DETECTION
    Publication number: 20140285267
    Abstract: In a portable radio transceiver, a power amplifier system includes a saturation detector that detects power amplifier saturation in response to duty cycle of the amplifier transistor collector voltage waveform. The saturation detection output signal can be used by a power control circuit to back off or reduce the amplification level of the power amplifier to avoid power amplifier control loop saturation.
    Type: Application

  • Apparatus and methods for biasing a power amplifier
    Patent number: 8362840
    Abstract: Apparatus and methods for biasing a power amplifier are provided. In one embodiment, a packaged circuit includes a power amplifier, a bond wire electrically connected between a system voltage source and a supply input of the power amplifier, a current source, a reference resistor electrically connected between the system voltage source and the current source, and a comparator. The comparator is configured to compare a sense voltage that is based on a voltage across the bond wire to a reference voltage that is based on a voltage across the reference resistor. The comparator is configured to generate a saturation control signal for clamping a bias current of the power amplifier when the sense voltage exceeds the reference voltage.
