Abstract:
An envelope tracking (ET) voltage tracker circuit and related power management circuit are provided. In examples discussed herein, an amplifier circuit(s) is configured to amplify a radio frequency (RF) signal(s) based on an ET modulated voltage provided by an ET voltage tracker circuit(s). The ET voltage tracker circuit(s) includes amplifier circuitry, which operates based on an ET target voltage and a bias current to generate the ET modulated voltage. However, the ET modulated voltage may deviate from the ET target voltage from time to time due to cross over distortions. In this regard, the ET voltage tracker circuit includes a bias modulation circuit to dynamically determine the cross over distortion and adjust the bias current to reduce deviations of the ET modulated voltage. As a result, the ET modulated voltage can track the ET target voltage more closely, thus helping to improve linearity performance and efficiency of the amplifier circuit(s).

Claim (Index 4):
The ET voltage tracker circuit of  claim 2  wherein the bias modulation circuit is further configured to determine whether the level of the alternating current is between the upper current threshold and the lower current threshold based on the time-variant target voltage envelope of the ET target voltage.
