Abstract:
An envelope tracking (ET) amplifier circuit is provided. The voltage mDPD circuit is provided in an ET amplifier circuit and configured to determine a voltage deviation relative to an ET modulated target voltage signal, execute an mDPD polynomial in one or more iterations to extract an mDPD coefficient(s), and adjust a time-variant target voltage envelope of the ET modulated target voltage signal based on the mDPD coefficient(s) extracted in each of the mDPD iterations to reduce the voltage deviation to a predefined threshold. By reducing the voltage deviation in the ET modulated voltage, it is possible improve linearity (e.g., gain linearity) of the ET amplifier circuit, which can lead to reduced power consumption and improved radio frequency (RF) performance.

Claim (Index 13):
The ET amplifier circuit of  claim 1  wherein:\n the at least one amplifier circuit is further configured to receive the RF signal in a carrier frequency at a signal input and output the RF signal in the carrier frequency at a signal output; \n the signal output is coupled to frequency-dependent impedance varying in proportion to the carrier frequency of the RF signal; and \n the voltage mDPD circuit is provided in the voltage input path when the frequency-dependent impedance coupled to the signal output varies less than twenty percent relative to the carrier frequency.
