Abstract:
An envelope tracking (ET) circuit is provided. The ET circuit includes an amplifier array(s) configured to amplify a radio frequency (RF) signal(s) based on a first input voltage and a second input voltage. The ET circuit includes a pair of tracker circuits each configured to generate a modulated voltage. Control circuitry couples a selected tracker circuit among the tracker circuits to provide a selected modulated voltage (e.g., ET modulated voltage) to the amplifier array(s) as the first input voltage. Depending on usage scenarios, the control circuitry also provides an ET modulated voltage, an average power tracking (APT) modulated voltage, or a constant voltage to the amplifier array(s) as the second input voltage. As such, the ET circuit can support the RF signal(s) modulated in a wide range of modulation bandwidth without compromising efficiency and/or increasing heat dissipation of the amplifier array(s).
