Abstract
Method and circuit for stabilizing the output power of a power amplifier, operated with signals having a large peak-to-average ratio and fed by a DC power supply with fluctuating output voltage. An allowable fluctuating range for the voltage output from the DC power supply and a constant voltage level are determined. A controllable voltage enhancement circuitry that can output an enhancement voltage is provided. The input of the voltage enhancement circuitry and a first DC supply path are connected to the output of the DC power supply. The output of the voltage enhancement circuitry is connected to a second DC supply path. While the instantaneous value of the fluctuating output voltage is lower than the constant voltage level, the voltage enhancement circuitry generates an enhancement voltage that causes the sum of the voltages supplied through the first and the second supply paths, to be identical to the constant voltage level.
