SYSTEM AND METHOD FOR SATURATION DETECTION AND COMPENSATION IN A POLAR TRANSMITTER
摘要
A system for saturation detection and compensation in a power amplifier includes a power amplifier, a closed power control loop configured to develop a power control signal (V<SUB>PC</SUB>), a comparator configured to receive the power control signal and a reference signal, the comparator also configured to determine whether the power amplifier is operating in a saturation mode, and power control circuitry configured to reduce the power control signal if the power amplifier is operating in a saturation mode.
