  • System and method for power amplifier control saturation detection and correction
    Patent number: 8666337
    Abstract: A system for power amplifier control saturation detection and correction includes a comparator configured to receive a power control signal and a detected power signal and generate a regulated voltage, a power amplifier configured to receive the regulated voltage and develop an output power, a power detector configured to sense the output power and develop the detected power signal, a saturation detector configured to receive the regulated voltage and a system voltage and determine whether the power amplifier is operating in a saturation mode during a transmit burst, and a current generator configured to reduce the power control signal when the power control signal exceeds a predetermined value and after expiration of a predetermined period of time, preventing the power control signal from exceeding the detected power signal.
    Type: Grant
