Patent ID: 8606311

Claim:
A method for adaptive bandwidth control in a mobile handset transmitter, comprising: using a power detector to detect an output power level generated by a power amplifier; generating an error signal responsive to a target power level and the output power level in a radio frequency sub-system of the mobile handset; and applying a bandwidth control signal to the error signal to generate a modified error signal in a closed control loop of an adaptive power controller in the mobile handset, the adaptive power controller controllably forwarding one of the modified error signal or a code to generate a power control signal in response to a desired range of transmit power, the adaptive power controller including a first shifter and a first scaler, said applying the bandwidth control signal to the error signal including applying a logarithmic control path to a filtered error signal, the logarithmic control path including a log converter, a second shifter, and a second scaler, the logarithmic control path responsive to a slope compensator coupled to the second shifter and the second scaler.
