Abstract
Current-mode control for radio-frequency (RF) power amplifiers. In some embodiments, an RF power amplifier control circuit can include a sensor configured to measure a base current of a power amplifier and generate a sensed current. The control circuit can further include a sensing node configured to receive a reference current and perform a current-mode operation with the sensed current to yield an error current. The control circuit can further include a control loop configured to generate a control signal based on the error current to adjust an operating parameter of the power amplifier.
