Abstract
A power correction module for use with an amplifier driving a load impedance is configured to sample the supply current and to cause a change in a control voltage, which corrects the supply voltage in response to a change in the load impedance. The supply voltage is corrected to cause the power amplifier to have a substantially constant output power. The power correction module is further configured to output a corrected peak voltage determined by an average value of the supply current.

A power correction module for use with an amplifier driving a load impedance, said power correction module comprising:
- an integrator configured to generate an average value of a supply current of said amplifier in response to changes in said load impedance;
- a correction factor block configured to receive said average value of said supply current and to provide a correction factor;
- wherein said correction factor is utilized to correct a supply voltage of said amplifier.
