摘要： An envelope tracking system includes an instantaneous amplitude circuitry, an instantaneous frequency circuitry, and a two-dimensional (2D) bias voltage selection circuitry. The instantaneous amplitude circuitry is configured to determine an instantaneous amplitude of a transmit signal. The instantaneous frequency circuitry is configured to determine an instantaneous frequency of the transmit signal. The two-dimensional (2D) bias voltage selection circuitry is configured to determine a bias voltage based on both the instantaneous amplitude and the instantaneous frequency of the transmit signal, and control power supply circuitry to supply the determined bias voltage to a power amplifier that is configured to amplify the transmit signal.

摘要： An apparatus for determining information on an amplitude error of a transmit signal includes at least one transmit path module, at least one feedback receive path module and at least one error determining module. The transmit path module generates a high frequency transmit signal based on a baseband transmit signal. The feedback receive path module generates a baseband feedback signal based on a high frequency feedback signal derived from the high frequency transmit signal. Further, the error determining module determines an error signal indicating information associated with an amplitude error of the high frequency transmit signal based on the baseband transmit signal and the baseband feedback signal. The error determining module comprises a feedback loop. This feedback loop of the error determining module comprises a feedback loop processing module. The feedback loop processing module generates a feedback loop output signal based on a feedback loop input signal and the baseband transmit signal.
