Abstract:
Nonlinear bandwidth compression circuitry is provided. In examples discussed herein, nonlinear bandwidth compression circuitry can be configured to modify predefined amplitude(s) of a predefined voltage waveform to generate modified amplitude(s) of a modified voltage waveform that is never less than the predefined amplitude(s) of the predefined voltage waveform. Thus, by providing the nonlinear bandwidth compression circuitry in an envelope tracking (ET) system to perform bandwidth compression, signal distortion(s) resulted from the bandwidth compression can be corrected (e.g., via digital pre-distortion). As such, the ET system can amplify a radio frequency (RF) signal having a signal modulation bandwidth exceeding a voltage modulation bandwidth limitation of the ET system, without degrading spectral performance of the RF signal.

Claim (Index 14):
The nonlinear bandwidth compression circuitry of  claim 10  wherein the feedback circuitry comprises:\n a feedback delay circuit configured to receive and delay the plurality of modified voltage amplitudes by a respective delta delay; and \n a feedback combiner configured to generate a plurality of feedback voltage amplitudes by reducing the plurality of modified voltage amplitudes by a respective delta voltage and provide the plurality of feedback voltage amplitudes to the feedback interface.
