POLAR TRANSMITTER HAVING A DYNAMICALLY CONTROLLED VOLTAGE REGULATOR AND METHOD FOR OPERATING SAME |
摘要 |
A supply voltage controlled power amplifier includes a power amplifier, a closed power control loop configured to generate a power control signal, and a voltage regulator coupled to the power control loop, the voltage regulator including a first regulator stage, a second regulator stage, and a peak detector, wherein an output of the second regulator stage is applied as a feedback signal to the first regulator stage and wherein an output of the first regulator stage is decreased to a level consistent with an output of the power amplifier and an additional operating buffer amount. |
